Abstract
Abstract The invention relates to optical systems incorporating means for dissecting a formation of light stemming from illuminated subject matter at one location within a telecommunications system and thereupon establishing a series of elemental light spot information for transmission to a second location for use in a reconstructing of an image of the initially illuminated subject matter.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
171 words
In an image projection and optical axis alignment control system, (a) a source of light representative of illuminated graphical information; (b) at least one acousto-optic light reflector having an acoustic-wave generator and an acoustic-optic interaction medium, said information and said medium positioned along a common optical axis of said system; (c) a source of ultrasonic frequency voltages and circuit means for controlling a connecting of individual voltages from said source to said generator for an establishing of corresponding acoustic wave light reflecting conditions within said medium and an effecting of optical path relationships, respectively, between selected portions of said information and said optical axis; (d) means for connecting a series of individual voltages from said source to said generator and an establishing of a corresponding series of said light reflecting conditions within said medium, said light reflecting conditions providing optical path relationships, respectively, between a series of predetermined portions of said information and said optical axis and an alignment of an optical image of each said portion with said optical axis.
Claim 2
Dependent Claim
171 words
In an image projection and optical axis alignment control system, (a) a source of light representative of illuminated graphical information; (b) at least one acousto-optic light reflector having an acoustic-wave generator and an acoustic-optic interaction medium, said information and said medium positioned along a common optical axis of said system; (c) a source of ultrasonic frequency voltages and circuit means for controlling a connecting of individual voltages from said source to said generator for an establishing of corresponding acoustic wave light reflecting conditions within said medium and an effecting of optical path relationships, respectively, between selected portions of said information and said optical axis; (d) means for connecting a series of individual voltages from said source to said generator and an establishing of a corresponding series of said light reflecting conditions within said medium, said light reflecting conditions providing optical path relationships, respectively, between a series of predetermined portions of said information and said optical axis and an alignment of an optical image of each said portion with said optical axis.
Claim 3
Dependent Claim
38 words
The invention as set forth in claim 1 including additionally a light-to-electrical effect converter positioned along said optical axis for receiving said optical image of each said portion and providing corresponding electrical signals at an output circuit thereof.
Claim 4
Dependent Claim
40 words
The invention as set forth in claim 2 including additionally a lens system positioned along said optical axis intermediate said interaction medium and said converter for projecting said optical image of each said portion along said axis toward said converter.
