[simpits-tech] Check this out for rear projection

[Rob Hommel]

Ido

Their holo lens is pretty neat it's a holograph of a fresnel lens. I had
heard of such a thing 20 years ago never seen it until now. How cool is
that?  Quite a few rear projection TV systems use this method. Imagine how
expensive a 3 meter X 4 meter ( roughly 9 ft X 12 ft) fresenel lens is. I
always appreciated the depth of field created by a fesnel lens. They have a
cool product someone should inquire as to price. Thanks for the link Ido.

Keep 'em Flying
