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
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.”
At Laser – World of Photonics in Munich (24 – 27 June 2019, Messe München) Forth Dimension Displays will present its updated range of Spatial Light Modulators (SLM) and microdisplays with new interface options.
The high resolution SLMs are known for their fast and stable structured light applications using binary phase modulation or binary amplitude modulation.
Please visit Hall B2 – Booth 129 to experience our new 2k x 2k, 4.1 MPixel microdisplay integrated into a 34° field of view monoviewer for high-end Near-To-Eye applications (AR, MR) applying the unique Time Domain Imaging technology.
Visit Forth Dimension Displays / Kopin at SPIE DCS 2019!
Kopin, a provider of high performance display components, subsystems and systems for the military, industrial, professional, medical and training markets, will be exhibiting at SPIE DCS 2019 from April 16-18th at the Baltimore Convention Center. Stop by booth #553 to see our latest high performance ruggedized microdisplay solutions.
Kopin’s offerings include LCD, FLCOS and OLED displays designed for high performance, long life and high reliability in demanding environments. Kopin’s display products are ideally suited for use in high brightness AR products, such as pilots’ helmets, rifle scopes, soldier visualization systems, image guided surgery and synthetic/embedded training.
Forth Dimension Displays’ specific products on the booth are the new 2k x 2k FLCOS, the RGB LED illuminator and a 3D demonstrator of the QXGA 2048 x 1536 pixel microdisplay.
13th March 2018, Scotland – Forth Dimension Displays has introduced a RGB-LED illuminator to its product portfolio. The illuminator works with all of Forth Dimension Displays’ reflective microdisplays and LED drivers. The well-characterized component enables a fast development of full colour optical modules.
The colour coordinates exceed the Rec 709 standard making it desirable for applications like electronic view finders (EVF) but also for Training and Simulation. The RGB-LED illuminator offers homogeneous colour and light output of 6000 cd/m² over a 22 x 16.5 mm aperture despite its small outline dimensions.
Greg Truman, CEO of ForthDD, said “ForthDD is closing a gap for our customers by introducing this RGB-LED illuminator. To create a high performance illuminator matching our microdislay technology is not an easy task. Therefore, this is an outstanding result of our internal R&D programme. Our customers can shorten the time to market for Near-To-Eye applications using the FLCOS display technology, indeed any reflective LCOS technology. ”
