Optical system for transmitting a source image

This invention describes an optical system that guides an image's light through a transparent channel using internal reflections. Light enters one end and exits the other, but first passes through a special internal optical element. This element redirects the light beams while ensuring that the angle of deflection is consistent for all incoming light rays, which helps maintain the image's integrity.

Why it matters: Filed before significant advancements in manufacturing precision and cost reduction for diffractive and holographic optical elements. These improvements could make the specialized deflector more feasible for compact display systems now.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedPrecision diffractive or holographic optical elements
