Lumus

The LOE is a patented [4] optical waveguide that makes use of multiple partial reflectors embedded in a single substrate to reflect a virtual image into the eye of the wearer. Specifically, the image is coupled into the LOE by a "Pod" (micro-display projector) that sits at the edge of the waveguide—in an eyeglass configuration, this is embedded in the temple of the glasses. The image travels through total internal reflection to the multiple array of partial reflectors and are reflected to the eye. While each partial reflector shows only a portion of the image, the optics are such that the wearer sees the combined array and perceives it as a single uniform image projected at infinity. The transparent display enables a virtual image to be seamlessly overlaid over the wearer's real world view. This is especially true when the source image comprises a black background with light color wording or symbology being displayed. Black is essentially see-through color, while lighter colored objects, symbols or characters appear to float in the wearer's line of sight. Conversely, full screen images like documents, internet pages, movies which are typically brighter colors can be displayed to look like a large virtual image floating a few meter's away from the wearer.

Lumus, with the LOE, has a single waveguide that works on all colors. The thickness of their one LOE is similar to the stack of multiple (one per red, green, and blue) thinner waveguides on HoloLens. They simply cut the waveguide’s entrance at an angle to get the light to enter (rather than use a color specific diffraction grating), and then they use a series of very specially designed partial mirrors to cause the light to exit.

The company builds reflective waveguides. The interesting, rather sleek pieces of display technology rely on microscopic etchings in transparent glass lenses that catch light being projected into their edges. While these systems are limited in how much of a viewer’s field-of-view they can fill, they are unparalleled in the small form factors they can reach and will likely be what powers your first pair of smart glasses.[5]

Development Kits

Dev Kit	Description	Image
DK-40[14]	The DK-40 is a fully comprehensive wireless, stand-alone monocular display development kit powered by the Lumus Optical Engine (OE) 40. The dev kit glasses have VGA resolution and 23° Field of View (FoV). The system contains an onboard OMAP processor running Android, embedded 9DoF motion sensor and a 5MP camera. The DK-40 enables true augmented reality capability by enabling direct image overlay over the wearer's main line-of-sight, coupled with the motion sensors and camera. Additionally, the unit comes with an SDK to program the onboard Application Processor (AP) and a client program that enables an Android phone to serve as a wireless remote control and mobile network back channel.

Lumus also has been working behind the scenes for years with a handful of Tier 1 consumer electronics manufacturers and tech companies, including Knapp AG, Thales, Daqri and Atheer.[16] The company aspires to be the Intel or the Qualcomm of the wearable display market—selling its optical engine modules as OEM components, while the Tier 1 companies will make the final products.[17]

• 2000: Lumus was founded by Dr. Yaakov Amitai to develop and market its Light-guide Optical Element (LOE) technology for eyewear displays (see-through wearable displays).
• 2008: The company started selling the PD-18: a top-down, transparent monocular display with SVGA resolution 32 degree field of view (FoV), and full color. The PD-18 and its derivative, the PD-14, were aimed at professional and military markets.[3]
• 2010: Lumus' technology received high level validation when the US Air Force selected Gentex's Scorpion Helmet Mounted Cueing System (which employs the Lumus PD-14), with Raytheon as the primary contractor, for the HMIT program for A-10 and F-16 Aircraft.[18] This display and contract win marked the first time a full color HMD was selected for combat aviation. Subsequently, Lumus' display as part of Thales Visionix's (formerly Gentex)Helmet Mounted Cueing System has been selected for the CHMDS / Air Soldier program. Once the roll out was completed on this program, Lumus displays represented the majority of HMDs deployed in the worldwide combat aviation market.[18]
