Abstract A thermistor bolometer having a bolometer housing is provided with an active thermistor flake mounted in the housing for providing a means of measuring radiation applied thereto. A light-emitting diode is mounted in the housing for applying radiation directly on the back of the active flake. The lightemitting diode provides a fully controllable source of radiant energy which may be utilized to test, calibrate, or function with the detector and the system in which the detector is employed in a variety of programmed ways. The thermistor bolometer may be of the immersed type, in which the active flake is mounted on an infrared window or lens, or may be of the solid-backed variety in which the solid-back substrate is transparent to the radiation applied to the back of the active flake by the light-emitting diode.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
73 words
A thermistor bolometer having a built-in source comprising a. a bolometer housing, b. an active thermistor flake mounted in said housing for measuring radiation applied thereto, and c. a built-in source means integrally mounted in said housing for applying a controllable amount of radiation directly on the back of said active flake which measures said controllable amount of radiation and thereby simulates a variety of conditions internally without resort to additional external structure.
Claim 2
Dependent Claim
73 words
A thermistor bolometer having a built-in source comprising a. a bolometer housing, b. an active thermistor flake mounted in said housing for measuring radiation applied thereto, and c. a built-in source means integrally mounted in said housing for applying a controllable amount of radiation directly on the back of said active flake which measures said controllable amount of radiation and thereby simulates a variety of conditions internally without resort to additional external structure.
