we have seen this somewhere but how about aiming beam on transparent glass.plastic etc so one could look through a field than direct aiming on eyeground!

The Times article was a bit misleading in this respect. Head-Mounted Displays work by creating a viewing aperture called an "exit pupil" which is to be aligned with the viewers eye. By controlling the apparent size of the "exit pupil" one can accommodate a broader range of viewing angles and positions (in the same way that a larger hole in a fence allows for more side to side motion than a small one). So the solution to accommodating movement whether from vibration or slippage of helmet or glasses or from movement of the eye is to expand the size of this "exit pupil". Microvision has demonstrated devices with "exit pupils" ranging from 1.5 millimeters to 15 millimeters. The specification for systems under development currently is in the range of 10 millimeters to 19 millimeters. While I wont go into the technical details of how we achieve this, the article seems to suggest that this continues to be a significant technological challenge for use of the system in the cockpit. We don't believe that this is the case, since our "exit pupil" should meet the required specification. Others on this thread who have seen the system, have seen monochrome systems with 7 millimeter "exit pupils" and color systems with 14 or 15 millimeter "exit pupils". I don't believe that any of our existing customers think that "exit pupil" alignment will be a technical challenge for us. By the way, warm regards to everyone. We are making outstanding progress in developing the technology and in developing relationships to deliver important visualization capabilities to customers. Congratulations to the brand new parents and a warm welcome to our newest follower of the thread. Regards, Rick

Jan, I was thinking more along the lines of a software fix for the vibration problem not unlike the sony cd system that eliminates skip when you hit a bump. The image could be momentarily stored and then compared compared to the original signal any differances could be digitally cancelled. The viration enviorment is very severe in the cockpit of a helicopter. In fact this is the limiting factor in how fast a Bell twin rotor can fly. the vibration is so severe that the pilot tends to rapidly fatigue. the "g" levels can approach 2 during high speed flight.
