Abstract
Abstract A scanning infrared display system capable of variable magnification and high spatial resolution measures the emitted infrared radiation caused by the scanning of a highly collimated energy source beam on the surface to be imaged. The resulting infrared emissions are collected with a high sensivity stationary detector. The display image is formed on a CRT by scanning the object with a raster pattern in synchronization with the CRT and modulating the Z axis CRT potential (brightness) with the infrared detection signal.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
168 words
A stimulated scanning infrared imaging system for scanning object surfaces comprising: a directed energy source for providing a collimated illuminating beam; illuminating beam deflection means for controlling illuminating beam movement over the surface of the object to be imaged; infrared detection means for providing a signal proportional to the intensity of the infrared radiation from the object scanned by said directed energy source; image recording means including means for recording image intensity coupled to said infrared detection means and means for controlling the position at which said image intensity is recorded; and beam control means coupled to said illuminating beam deflector means and said means for controlling the position at which said image intensity is recorded, for synchronously driving said illuminating beam and said means for controlling the position at which said image intensity sis recorded, to provide an infrared image of the surface scanned, the ratio of said illuminating beam movement to the synchronized control of the position at which said image is recorded, controlling image magnification.
Claim 2
Dependent Claim
168 words
A stimulated scanning infrared imaging system for scanning object surfaces comprising: a directed energy source for providing a collimated illuminating beam; illuminating beam deflection means for controlling illuminating beam movement over the surface of the object to be imaged; infrared detection means for providing a signal proportional to the intensity of the infrared radiation from the object scanned by said directed energy source; image recording means including means for recording image intensity coupled to said infrared detection means and means for controlling the position at which said image intensity is recorded; and beam control means coupled to said illuminating beam deflector means and said means for controlling the position at which said image intensity is recorded, for synchronously driving said illuminating beam and said means for controlling the position at which said image intensity sis recorded, to provide an infrared image of the surface scanned, the ratio of said illuminating beam movement to the synchronized control of the position at which said image is recorded, controlling image magnification.
Claim 3
Dependent Claim
35 words
The system of claim 1 wherein said imaging display means comprises a cathode ray tube display means and said means for controlling image intensity comprises the electron beam in the cathode ray tube display means.
