Abstract

Abstract A column of infrared detectors are repetitively optically scanned across annfrared scene. The outputs of the detectors are fed to a viewing matrix of light emitters consisting of a plurality of columns of detectors, each column having light emitters corresponding to respective detectors. As the detectors are scanned across the scene, successive columns of detectors are energized or enabled such that the light emitted by the individual emitters is directly related to the infrared radiation falling on a corresponding detector. The image may thus be directly viewed by an observer. An alternate system employs a storage matrix having light detectors corresponding to the emitters of the viewing matrix such that the output of the viewing matrix, instead of being directly viewed, is stored and is then read out in a normal television raster to provide a video signal for distant television viewing.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 91 words
An infrared viewing system including: a column of infrared detectors each having an output; means for scanning said column with respect to an infrared image; a display matrix having a plurality of columns of light emitters, each column having emitters corresponding to respective detectors; and means for sequentially connecting the outputs of the columns of detectors to successive columns of the matrix whereby respective detector outputs of the column of detectors are connected to corresponding light emitters in the columns of light emitters as the scanning of the infrared image occurs.
Claim 2
Dependent Claim 91 words
An infrared viewing system including: a column of infrared detectors each having an output; means for scanning said column with respect to an infrared image; a display matrix having a plurality of columns of light emitters, each column having emitters corresponding to respective detectors; and means for sequentially connecting the outputs of the columns of detectors to successive columns of the matrix whereby respective detector outputs of the column of detectors are connected to corresponding light emitters in the columns of light emitters as the scanning of the infrared image occurs.
Claim 3
Dependent Claim 45 words
The system as recited in claim 1 further including a conversion matrix having visible light detectors corresponding to the light emitters of said display matrix, and means for sequentially determing the states of the visible light detectors and providing an output signal in accordance therewith.
