Abstract
Abstract The invention relates to a device for composing an infrared image, which device is provided with a rotating body for scanning the infrared object to be imaged, and for recomposing the visible image. The rotating body comprises a disc with at least five abutting, outwardly reflecting roof-edge mirrors, regularly provided on the periphery of the disc.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
143 words
A device for composing an infrared image provided with a rotating reflecting body for scanning an object line by line, a detector placed near that body and a reproduction system synchronised with the scanning movement, wherein the body comprises a disc with at least five abutting outwardly reflecting roof-edge mirrors, regularly provided on the periphery of the disc, wherein the basic angles of the roof-edge mirrors are chosen such that the reflecting surfaces of two mirrors adjacent one another are at right angles, the apex angle of each said mirror therefore being determined by the formula: 90* - (360*/n) in which n represents at least five mirrors, and wherein, with the aid of an optical system, at least one radiation detector and at least one crater lamp is imaged on the cylinder periphery through the cams of the roofs of the roof-edge mirrors.

Claim 3
Dependent Claim
35 words
A device according to claim 1, wherein with the aid of an optical system at least one radiation detector is imaged on the cylinder periphery through the cams of the roofs of the roof-edge mirrors.
Claim 4
Dependent Claim
31 words
A device according to claim 1 wherein a mechanical shaft of the disc makes an angle other than 90* with the optical axes of the imaging systems of the crater lamps.
Claim 5
Dependent Claim
28 words
A device according to claim 1 wherein the imaging systems of the detectors and the crater lamps are mounted to a yoke movable with respect to the disc.
Claim 6
Dependent Claim
35 words
A device according to claim 4, wherein the yoke can move in a plane through the shaft of the disc and wherein means are provided for allowing that movement to proceed with a sawtooth motion.
