Virtual retinal display

Built a retinal projector last night just for fun (and because i was curious what kind of image quality could be achieved).

WARNING : DONT DO THIS UNLESS YOU KNOW WHAT YOU ARE DOING. SHINING LIGHT INTO YOUR EYES CAN BE SERIOUSLY DANGEROUS. DO YOUR RESEARCH BEFORE TRYING ANYTHING LIKE THIS.

Notes:
Works Well, Produces a crystal clear image straight into your eyeball. unfortunately it seems that the alignment of everything and positioning of the eye needs to be to accurate for any practical use. The plan was to come up with a setup allowing us to make some kind of FPV goggles with this however without a lot of work this will not be stable enough on your head to remain reliable. the focal point must pass through your iris so a few mm of movement will cause you to loose the picture.

How It Works:
Image is produced by the Pico Projector. it passes through a variable ND Filter made of 2 linear polarising lenses, passes through the glass, reflects off the concave internal side of the magnifier (for refocusing) before finally reflecting off the glass slide and into the users eye (placed above).
