RGB-LED illuminator introduced by Forth Dimension Displays

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. ”

Forth Dimension Displays’ Wide Temperature Range SXGA microdisplay now shipping

7th September 2017, Scotland – Forth Dimension Displays is shipping this week the first lot of extended temperature range SXGA (1280 x 1024) microdisplays. This marks the successful conclusion of an internal R&D programme to widen the temperature range of the SXGA microdisplay at both, the lower and the upper ends. The introduction of a new ferroelectric liquid crystal (FLC) mixture now enables the microdisplays to be used in additional outdoor and defence applications. The parts shipped this week include the R5 drive boards and will be used in an aircraft head-up display (HUD).

The FLC is a key component in ForthDD’s unique display technology ferroelectric liquid crystal on silicon (FLCOS) allowing electro-optic switching speed of several kHz at low voltage. The new FLC mixture is compatible with other existing and future microdisplays of ForthDD.

Greg Truman, CEO of ForthDD, said “ForthDD is proud to announce our extended temperature range microdisplay. It is quite a challenge for a small manufacturing company to improve in-house one of the key materials, in this case the FLC mixture. Building on this learning curve, we are now capable of performing other FLC material optimisations and to meet tough environmental requirements. Our customers can now pursue a wide range of outdoor and defence applications using the FLCOS display technology. ”

Forth Dimension Displays’ 3 MPixel SLM designed into Lumaxis’ Structured Light Projector for precision 3D Optical Inspection

 28th August 2017, Scotland – Lumaxis of Reston, Virginia has successfully integrated in their new Structured Light Projectors (SLP) the 3 MPixel (2048 x 1536 pixels) Spatial Light Modulator (SLM) from Forth Dimension Displays. SLPs are a key component of 3D optical inspection, for example in 3D automated optical inspection (3D AOI) equipment. 3D AOI is rapidly replacing 2D AOI in the quality control of printed circuit board (PCB) manufacturing. The ability to use 3D AOI to measure in-line SMT components in all three dimensions on every PCB enables companies to improve yields and product quality while reducing wastage and costs.

ForthDD’s QXGA-3DM  is a fast switching, all digital, high performance reflective SLM product. Designed for 3D optical metrology, the QXGA-3DM features the industry proven Time Domain Imaging™ display with a 3D metrology specific display drive interface.

Lumaxis is a division of NVIS Inc. which has long established capabilities in the design and manufacture of optical systems based on Forth Dimension Displays’ microdisplays. Lumaxis will manufacture the SLPs in the US combining ForthDD’s QXGA-3DM SLM with an LED illuminator and LED drive electronics, optical components and housing. The SLP will deliver precise, high resolution (25 line pairs/mm) structured light patterns over a 41mm x 35mm field of view. This combination of the products and expertise from the two companies will allow manufacturers of 3D optical metrology equipment to reduce their time to market and benefit from an established, experienced SLP supply chain.

Marc Foglia, CEO of NVIS said “3D optical metrology using structured light projection is an enabling technology for quality control in various lines of manufacturing. In particular, the market for 3D AOI machines is rapidly growing with increasing demand on high precision and the ability to measure small feature sizes. Combining ForthDD’s SLM and Lumaxis’ projection technology will result in a 3D optical metrology solution for demanding customers.”

Greg Truman, CEO of ForthDD said “The market for 3D optical inspection is growing rapidly in all parts of the World. ForthDD has a very strong position in the 3D AOI market, supplying leading manufacturers in Germany, Japan, China and South Korea. Working closely with Lumaxis, ForthDD intends to expand this position supplying into the ultrahigh precision market.”

Forth Dimension Displays to attend Nepcon South China

Forth Dimension Displays (ForthDD), a leading provider of high-resolution Liquid Crystal On Silicon (LCOS) Microdisplays and Spatial Light Modulators (SLMs) will be attending at Nepcon South China in Shenzhen.

ForthDD’s team is about to depart for the Nepcon South China exhibition, the leading show for PCB inspection equipment in the Hong Kong area. Held from 29 – 31 August 2017 in Shenzhen, ForthDD will meet current and new customers engaged in the field of 3D optical metrology like 3D Automated Optical Inspection (AOI) and 3D Solder Paste Inspection (SPI).

The 1.3MPixel SXGA-3DM SLM has a leading position in the in-line 3D AOI PCB inspection and measurement market. Integrated in structured light projectors it’s showing multi-frequency Moiré patterns at speeds enabling in-line inspection. The more recent 2048 x 1536 pixel QXGA-3DM SLM builds upon this track record by enabling even higher resolution structured light projectors to be built.

QXGA 3DM Forth Dimension Displays

The SXGA-3DM and the QXGA-3DM combine an industry proven SLM technology with a specific non-video drive interface dedicated to metrology applications. The drive interface is capable of storing up to 1024 full resolution images. Bi-directional trigger signals ensure accurate synchronization with other system components such as cameras, light sources and translation tables.

Forth Dimension Displays and LightTrans collaborating on phase modulated SLMs

27th September 2016 – Forth Dimension Displays (ForthDD), leading supplier of fast binary spatial light modulators (SLMs), and LightTrans, vendor of the optical design software VirtualLab Fusion, are collaborating on an adaptation of LightTrans’ simulation software. The new capabilities in VirtualLab Fusion will encompass adding support for the high speed binary phase modulators offered by ForthDD.

ForthDD’s binary SLM offers QXGA resolution (2048 x 1536 pixels) resolution at speeds up to 4.5 kHz with a pixel pitch of 8.2 μm based on ferroelectric liquid crystal on silicon (FLCOS) technology. The drive interface can either support video, using the DisplayPort standard, or a dedicated flash memory based interface interface calling off up to 1024 binary phase masks from the on-board memory and controlled using flexible trigger ports.

The PC-based VirtualLab Fusion allows optical engineers to conveniently convert imagery into phase masks. Therefore, the software provides reliable, fast and flexible tools for the design of adaptive optical systems. Phase masks can be computed and the data can be transferred to the SLM. VirtualLab Fusion enables the analysis and optimization of the entire adaptive laser system containing complex laser sources, beam delivery optics and the diffractive SLM.

Greg Truman, CEO of Forth Dimension Displays, is full of optimism: “We are delighted to be able to support customers using our phase modulation SLMs in their R&D work. By working with our new partner LightTrans, and their enabling, user-friendly software, it will be easier and faster for scientists and engineers to build systems using our SLMs.”

Dr. Michael Kuhn, CEO of LightTrans, says: “The powerful design algorithms of VirtualLab Fusion for phase masks and the physical optics modelling for entire laser systems will considerably enhance many applications based on SLMs. It is a pleasure for us to collaborate with Forth Dimension Displays and to provide new innovative optical solutions to our customers.”
