Abstract
Abstract Temperature of a body is determined by measuring the infrared radiation emitted by the body while simultaneously viewing the body. The body is viewed through a viewing cone with visible wavelength light conducted to the body from a remote source by optical fibers. Infrared radiation emitted by the body is collected by infrared-transmitting fibers which conduct the infrared energy to a remote sensor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
168 words
Apparatus for simultaneously illuminating and viewing a body while detecting infrared radiation emitted by the body comprising: (a) a visible light source; (b) an infrared radiation detector; (c) a viewing channel arranged to permit optical viewing therethrough along a first axis in a first direction toward a body which emits infrared radiation; (d) visible wavelength conduits operatively associated with said viewing channel, each having one end arranged to receive radiation from said visible light source and the other end arranged to radiate visible wavelength light substantially parallel with the axis of said viewing channel and toward said body; (e) infrared wavelength conduits operatively associated with said viewing channel, each having one end arranged to receive infrared radiation from said body and direct said infrared radiation to said infrared radiation detector without obstructing the visual path through said viewing channel and (f) means for producing a graphic image representative of the temperature indicative of the infrared radiation directed onto said infrared radiation detector for display within said viewing channel.
Claim 2
Dependent Claim
168 words
Apparatus for simultaneously illuminating and viewing a body while detecting infrared radiation emitted by the body comprising: (a) a visible light source; (b) an infrared radiation detector; (c) a viewing channel arranged to permit optical viewing therethrough along a first axis in a first direction toward a body which emits infrared radiation; (d) visible wavelength conduits operatively associated with said viewing channel, each having one end arranged to receive radiation from said visible light source and the other end arranged to radiate visible wavelength light substantially parallel with the axis of said viewing channel and toward said body; (e) infrared wavelength conduits operatively associated with said viewing channel, each having one end arranged to receive infrared radiation from said body and direct said infrared radiation to said infrared radiation detector without obstructing the visual path through said viewing channel and (f) means for producing a graphic image representative of the temperature indicative of the infrared radiation directed onto said infrared radiation detector for display within said viewing channel.
Claim 3
Dependent Claim
17 words
Apparatus as defined in claim 1 wherein said infrared wavelength conduits are flexible fibers of chalcogenide glass.
Claim 4
Dependent Claim
97 words
Apparatus as defined in claim 1 wherein said visible wavelength conduits and said infrared wavelength conduits are glass fibers with input ends and output ends, the input ends of the visible wavelength conduits arranged to radiate visible wavelength light from a first end of the viewing channel and illuminate at least a portion of said body and the input ends of the infrared wavelength conduits arranged adjacent said first end of the viewing channel to collect infrared radiation emitted from the portion of said body illuminated by the visible wavelength light radiated from said visible wavelength conduits.
Claim 5
Dependent Claim
179 words
Apparatus for collecting infrared energy radiated by a body while simultaneously optically viewing the body comprising: (a) a viewing assembly having a central axis adapted to permit visual observation of a body aligned with said central axis; (b) a first conduit operatively associated with said viewing assembly arranged to transmit visible wavelength optical energy from a remote source toward said body in a direction substantially parallel with said central axis; (c) a second conduit operatively associated with said viewing assembly arranged to receive infrared energy radiated by said body and transmit such infrared energy to a detector remote from said body; (d) a lens comprising part of said viewing assembly and aligned with said central axis to permit optical viewing of said body through said lens; (e) said detector being arranged to detect infrared energy transmitted thereto by said second conduit; and (f) means for producing a graphic image representative of the temperature of said body as indicated by the infrared energy radiated by said body and detected by said detector and displaying said graphic image through said lens.
Claim 6
Dependent Claim
