3i’s new Microscopes use binary SLMs

Forth Dimension Displays’ LCOS-based Fast Switching Binary Modulators enable new Ultra-Fast, High-Resolution Microscopes

Forth Dimension Displays (ForthDD) and Intelligent Imaging Innovations (3i), a Colorado-based manufacturer of fluorescence microscope systems for biomedical research, expanded their collaboration with the launch of 3i’s Cleared Tissue LightSheet (CTLS) product. CTLS can image whole organs at high speed by illuminating them with structured light using ForthDD’s proprietary high-resolution, fast Spatial Light Modulators (SLMs).

Similar to other fluorescence microscope techniques, CTLS uses laser light to stimulate fluorescence emission from genetically-labelled – or stained – tissue to form an image of the specimen. The Cleared Tissue LightSheet creates a finely focused sheet of light for optical sectioning, then uses ForthDD’s SLM to rapidly shift the thinnest portion of the sheet in synchronization with the microscope and camera resulting in ultra-fast and high-resolution imaging of large specimens. Piezoelectric stages move the specimen in x, y, and z directions with sub-micron precision. The emission from the fluorescent markers in the specimen is recorded by a camera and 3i SlideBook software automatically and precisely reconstructs the biological structure in 3D for further analysis. Hundreds to thousands of images are required to create a 3D image of the tissue sample.

3i also integrates ForthDD’s SLMs into their live cell imaging system Lattice LightSheet (LLS). The SLM is used to create an ultra-thin lattice light sheet which can be quickly adjusted for biological conditions on-the-fly due to the flexibility and speed of ForthDD’s SLM. LLS enables spatiotemporal super-resolution imaging of dynamic cellular processes with ultra-fast capture speeds and high resolution, while limiting laser light damage to the cells. LLS can also be used to perform structured illumination microscopy (SIM), a super-resolution technique that improves the spatial resolution to the low 100’s of nanometers.

“Spatial light modulators provide outstanding value, increasing the speed and resolution of research microscopes,” Brian Bodensteiner, Vice President Development of 3i said, “ForthDD’s SLM technology is designed to allow for the flexibility, performance, and hardware-timing demanded by advanced light microscopy applications.”

Greg Truman, CEO of ForthDD said, “The development of super-resolution techniques has been a remarkable achievement and ForthDD is very pleased that our fast binary SLMs are a key enabler for microscope developers and biologists around the globe. The new microscopes are now being used in the life sciences industry to enhance the understanding of the biological structures. ForthDD is committed to supporting its customers to create their most advanced products.”

Forth Dimension Displays Develops 2560 x 1440 FLCOS Microdisplay for Rugged Applications

Forth Dimension Displays Develops 2560 x 1440 FLCOS Microdisplay for Rugged Applications

Breakthrough 0.95-Inch Display using Wide-Temperature Range Ferroelectric Liquid Crystal

Kopin Corporation (NASDAQ: KOPN), a leading provider of innovative wearable computing technologies and solutions, today announced that its wholly-owned subsidiary Forth Dimension Displays (ForthDD) has developed a new WQHD (2560 x 1440 resolution) full-color Ferroelectric Liquid Crystal on Silicon (FLCOS) microdisplay for use in extreme temperature and shock environments. The new display incorporates ForthDD’s proprietary Wide Temperature Range Ferroelectric Liquid Crystal (WTR FLC) material to operate over extended temperature ranges, which enables it to be used in a variety of previously unsupported rugged applications such as automotive, defense and avionics.

“FLCOS displays provide superior fill factor, color purity, and fast switching speeds which produces very high quality imagery, but historically ferroelectric liquid crystals have been restricted to limited temperature range applications,” said Greg Truman, Forth Dimension Displays’ Managing Director. “The breakthrough provided by our WTR FLC performance together with the very high resolution of the our WQHD display allows us to support resolutions that exceed the limits of our Active Matrix Liquid Crystal Displays (AMLCD) and brightness levels that exceed the capability of Organic Light Emitting Diode displays (OLEDs). The innovation provided by our WTR FLC, which has passed environmental and reliability tests, opens up many new applications and markets including high volume US defense product applications.”

The WQHD display with 8.2-micron pixels utilizes ForthDD’s patented Time Domain Imaging (TDI™) technique to produce superior full color imagery and no perceptible motion artifacts. The specialized ultra-fast ForthDD FLCOS overcomes the motion artifacts of standard Liquid Crystal on Silicon (LCOS) displays. The display is generally available as a Board Level Product with fully integrated driver and optional illumination subsystem later in 2020. WQHD displays have now been fully tested and are undergoing system qualification with the first defense customer as a part of fully integrated Kopin display systems, which incorporate the display with Kopin electronics, optics and system packaging elements.

“The availability of the new WQHD display gives us another microdisplay technology in our defense and enterprise product offerings and is ideal for use in systems needing cutting-edge high resolution and bright full color video images without color breakup,” said Bill Maffucci, Kopin’s Vice President/General Manager of Government and Professional Products. “The unique WQHD display is an excellent complement to our AMLCD displays which are primarily for soldier centric systems. As a result, it provides Kopin with the opportunity to open up new markets such as ground vehicle platforms. These market segments have been largely supported by CRT technology and represent a significant potential growth area facilitated by the new WQHD display.”

Forth Dimension Displays and VividQ Collaborate on Holographic 3D Mixed Reality Headset

Forth Dimension Displays and VividQ Collaborate on Holographic 3D Mixed Reality Headset

Forth Dimension Displays Limited, (ForthDD), a wholly owned subsidiary of Kopin Corporation, is collaborating with VividQ on holographic 3D in mixed reality headsets that provide real depth perception. VividQ, based in London and Cambridge, England offers algorithms to generate full colour 3D holographic images in real time using phase modulation technology. ForthDD is a manufacturer of fast high-resolution Spatial Light Modulators (SLMs) based on ferroelectric liquid crystal on silicon designed to offer phase modulation at speeds well below 1 ms.

Augmented Reality (AR) and the related areas of Virtual Reality (VR) and Mixed Reality (MR) are widely seen as the next step in interaction with digital information. However, there are still several challenging issues, especially the representation of true 3D imagery. AR headsets today are largely unable to display images across more than two distinct focal planes. This causes virtual objects to jump in the viewer’s perception when they move across varying depths. It also triggers nausea due to the lack of correct eye convergence, as there is a gap between the position of an object expected by the human visual system and the actual position in the virtual image. Computer-generated holography (CGH) with true 3D imagery will eliminate the nausea caused by this accommodation-vergence conflict.

Darran Milne, CEO of VividQ said, “VividQ’s engine for real-time 3D hologram generation finally allows CGH to break out of the lab to be used in consumer devices like mixed reality headsets or head-up displays. We are committed to becoming the software foundation that powers the first generation of true holographic 3D display devices. To demonstrate the huge potential of this technology, we have recently created the world’s first fully holographic MR headset, which we showcased at SPIE Photonics West in San Francisco, 5-7 February 2019.”

“The key differentiator in these headsets is that ForthDD’s SLMs are used as phase modulators, not amplitude modulators,” said Greg Truman, CEO of ForthDD. “CGH relies on the SLM modulating the phase of incoming laser light and projecting diffracted light into the user’s eye. Unlike microdisplays using amplitude modulation, CGH shows true 3D natural vision-like overlay of imagery in AR headsets. Our 2048 x 1536 pixel QXGA SLM is a fast switching, all digital, high performance reflective SLM product designed for binary phase modulation. In real-time holography applications, ForthDD’s Time Domain Imaging™ technology and CGH-specific image generation are successfully combined and delivered.”

Forth Dimension Displays releases an improved metrology interface for its 1.3 MPixel SXGA SLM

Forth Dimension Displays, a leading supplier of Spatial Light Modulators (SLM) into the in-line 3D metrology market, has delivered the much improved metrology-specific interface board R12 to the first customers.

These customers are updating their existing product to make best use of the smaller footprint of the R12 interface board, the capability to “daisy-chain” multiple boards and the new, size-matching high power LED drive board. Typically, a 3D metrology application requires to trigger several off-axis structured light projectors sequentially in a daisy-chain to enable shadow-free image analysis. The high power LED driver board matches to today’s brightest and most compact LEDs. Increasing the projector’s brightness reduces the camera exposure times for in-line 3D AOI and 3D SPI significantly, therefore allowing higher in-line inspection speed. The optional LED drive piggy-backs onto the R12 board as shown below, making it a very compact system to be integrated into the structured light projector.

The R12-LED board combination drives the 1 MPixel, WXGA SLM and the 1.3 MPixel, SXGA SLM, both renowned for its fast and precise digital performance. The metrology line-up is completed with the 3.1 MPixel, QXGA-3DM system for an even more detailed stripe projection. The QXGA-3DM can also be equipped with the LED drive board.

As always Forth Dimension Displays offers the complete range of product documentation with the development kit and support for projector design by our application engineering team.
