Meant to be Seen

I'd like to DIY the PinMR optic system as demoed by letinAR. It requires precision alignment of several small mirrors, each reflecting a partially overlapping elemental image from a micro-display. The mirrors are placed closer to the eye than the lens's focal length, acting as a pinhole to negate the need for focusing optics. Using multiple mirrors increases the field of view and also increases the optical efficiency of the virtual image.
