Abstract
Abstract Image transmitting apparatus including a light collimating device for receiving image bearing light rays focused onto one side thereof and operative to project collimated image carrying rays from a second side thereof to travel along a predetermined transmission path, which transmission path may be formed by various lenses and mirrors. The image carrying light rays are received at a display location and are magnified to be projected onto a display panel to display the resultant display image.

Claim 2
Dependent Claim
223 words
Image transmitting apparatus for transmitting light between remote locations, said apparatus comprising: first and second housings; first and second optically reflective conversion sheet means mounted on said respective first and second housings for receipt of low intensity image bearing light from respective first and second objects and locally operative in response to the intensity of the image bearing light to proportionately vary the optical reflectivity thereof; first and second intensified light sources mounted on said respective first and second housings for directing high intensity light onto said respective second and first conversion sheet means for reflection therefrom as respective first and second high intensity image transmitting light having local intensities corresponding with the local reflectivity of such respective second and first conversion sheet means; first and second light transmitting means mounted on said respective first and second housings for receiving the respective second and first high intensity image transmitting light reflected from the respective first and second conversion sheet means and transmitting it along respective paths to said respective second and first housings; and first and second display panel means on said respective first and second housings for receiving said respective second and first high intensity image transmitting light from said respective first and second transmitting means and operative in response thereto to display images corresponding with the respective second and first objects.
Claim 3
Dependent Claim
114 words
Image transmitting apparatus as set forth in claim 1 wherein: said first conversion sheet means includes a generally transparent dipolar suspension plate including suspension fluid contained therein and substantially opaque elongated ferromagnetic particles suspended in random fashion in said fluid, said particles being characterized in that they are responsive to various levels of electrical field applied thereto to align with the lines of force of said field to a degree proportionate to the local strength of said field, said first sheet means further including electrical control means for generation of said electrical field and responsive to the local intensity of said image bearing light to vary the local strength of said field proportionate thereto.
Claim 4
Dependent Claim
43 words
Image transmitting apparatus as set forth in claim 1 that includes: image transfer means mounted on said first housing adjacent said conversion sheet means for transferring said low intensity image bearing light from said object for projection on said first conversion sheet means.
Claim 5
Dependent Claim
127 words
Image transmitting apparatus as set forth in claim 1 that includes: object lens means on said first housing and interposed between said first object and said first conversion sheet means, said first conversion sheet being disposed at an oblique angle with respect to the optical axis of said lens means; image transfer means on said first housing and including a plurality of parallel optical fibers disposed in side-by-side relationship and terminating at their respective one ends in a plane disposed perpendicularly to the optical axis of said lens means and arranged in the focal plane of said lens means and terminating at their opposite extremities in an oblique plane extending obliquely to said axis and wherein; said first conversion sheet means is disposed on said oblique plane.
Claim 6
Dependent Claim
143 words
