The International Technology Exhibition will be held in Yokohama (2-4 December 2020, Pacifica) with Forth Dimension Displays presenting its expanding range of Spatial Light Modulators (SLM) and microdisplays at booth #25.
The high resolution SLMs are based on ferroelectric liquid crystal technology. The SLMs are applied in system for fast and stable structuring of light using binary phase modulation or binary amplitude modulation.
Please discuss your application idea with our East Asia representative Alex Bird of Forte Solution Asia.
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.”
At Photonics West 2020 in San Francisco (4-6 February 2020, Moscone Centre) Forth Dimension Displays will present its expanding range of Spatial Light Modulators (SLM) and microdisplays.
The high resolution SLMs based on ferroelectric liquid crystal technology are known for their fast and stable structured light applications using binary phase modulation or binary amplitude modulation.
Please visit Booth 1841 – South Hall inside the Scottish Pavilion- to experience the 2k x 2k, 4.1MPixel microdisplay integrated into a monoviewer. We will also present a structured light projector and a binary phase modulation set-up.
4th July 2019 – Forth Dimension Displays is pleased to be sponsoring this years FLC conference in Boulder, Colorado.
Due to be held between 4 – 7 August 2019 at the University of Colorado in Boulder, the conference brings together leading experts in the field of Ferroelectric Liquid Crystals (FLC). Boulder has been one of the hotbeds of research into physics, chemistry and applications of FLCs for over 30 years. Forth Dimension Displays’ microdisplays and spatial light modulators (SLM) are based on the electro-optics of FLCs. Therefore, it is very befitting to support continuous research into the fascinating properties of this material. At this conference Forth Dimension Displays will be sponsoring the Best Student Poster Award.
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.
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.”
