Abstract
Abstract A system is provided for time multiplexing a plurality of optical scanners. The system includes at least two electro-optical detection systems, each including means for receiving an image of an object and producing an electrical signal output in response to the sensing of an image, mirror means movable to scan a first location and reflect an image of any object at the first location to the first detection system and to scan a second location to reflect an image of any object at the second location to the second detection system and means for moving the mirror to continuously scan the first and second locations. The system further includes means for processing the electrical signal outputs of the detection system and switch means for alternately connecting the outputs of the first and second detection system to the processing means.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
155 words
A multiplexing optical scanner system including: a first electro-optical detection system including means for receiving an image of an object and producing an electrical signal output in response to the sensing of an image; a second electrooptical detection system including means for receiving an image of an object and producing an electrical signal in response to the sensing of an image; a single scanner including mirror means movable to alternately scan a first location and reflect an image of any object at said first location to said first detection system and to scan a second location and reflect an image of any object at said second location to said second detection system; means for moving said mirror means to scan said first and second locations; means for processing the electrical signal outputs of said detection systems; and switch means for alternately connecting the outputs of said first and second detection systems to said processing means.
Claim 2
Dependent Claim
155 words
A multiplexing optical scanner system including: a first electro-optical detection system including means for receiving an image of an object and producing an electrical signal output in response to the sensing of an image; a second electrooptical detection system including means for receiving an image of an object and producing an electrical signal in response to the sensing of an image; a single scanner including mirror means movable to alternately scan a first location and reflect an image of any object at said first location to said first detection system and to scan a second location and reflect an image of any object at said second location to said second detection system; means for moving said mirror means to scan said first and second locations; means for processing the electrical signal outputs of said detection systems; and switch means for alternately connecting the outputs of said first and second detection systems to said processing means.
Claim 3
Dependent Claim
45 words
The system in accordance with claim 1 wherein said mirror means includes: a wheel, a plurality of mirror segments disposed about the periphery of said wheel, means for rotating said wheel, and said detection systems are focused on said wheel angularly displaced from each other.
Claim 4
Dependent Claim
44 words
The system in accordance with claim 1 wherein said mirror means includes a pivotally mounted two-sided mirror, said detection systems are focused on opposite sides of said mirror, pivot means disposed between said detection systems, and means for oscillating said mirror about said pivot.
Claim 5
Dependent Claim
27 words
The system in accordance with claim 3 wherein said mirror is disposed in a plane defining an acute angle with a line extending between said detection systems.
