 Should we hear the SID display week and the who are you? I'm Richard Austin president and CTO of Gamma Scientific So what are you showing right here? This is our newest near-eye display measurement system that Can measure all the important parameters parameters for display for near-eye augmented reality and virtual reality displays So we have a small entrance people right here That mimics the eyes entrance people. This is five millimeters and it can be changed down to two millimeter And it's approaching this virtual reality display to measure things like field of view luminance uniformity color uniformity and Also modulation transfer function or contrast measurement depth We can do it in two different configurations both pupil rotation About the center of the pupil right here or we can pick the rotation point to be 13 millimeters back And show how the human eye actually sees the display as the eye pupil rotates back and forth through the qualified viewing space So we can measure virtual Reality type displays or we can measure the augmented reality type displays like this pair of BT 200 glasses So the robot system has very high positioning precision 25 microns and also has very high precision and pointing direction a hundredth of degree precision So with this small optical front-end we can rotate the entrance pupil to mimic the human eye entrance pupil rotation through a hundred and sixty degree angle and cover almost I don't know if there's another AR display that covers more than a hundred and sixty degrees So I think we can cover all types of displays that are currently offered So the eyes on last year you you showed it the first time Yes, so it's been going on for a little more than a year or how's it going with the the market adopting this? the changes that we've made to the optical Size of the entrance pupil area here that allows us to cover a hundred and sixty degree field of view It's really a key Additional feature that the market was asking for that we can meet now Nice, so now this is great for AR VR And heads up displays for automobiles also So we can position this pupil at the left or right eye pupil position of a driver and actually look at different driver positions in a modified mocked up driving Scenario and map the whole qualified viewing space of a heads up display Measurement system and your company has been doing a measurement systems for many different markets for a long time before We've been doing heads up display measurement systems for over 40 years starting with military programs the f-16 Program was the first one that we know built Measurement equipment for All right, so you're like the top experts in the heads up display. I Wouldn't say I was the top expert in that but we know In very fine details what to do in terms of measuring optical systems for virtual reality Disguise and virtual image displays
