Abstract: An infrared (IR) thermometer for performing temperature measurement of an object without having contact with the object. The IR thermometer comprises at least one IR sensing element which, upon exposure to IR radiation, produces a response. The IR sensing element comprises a flat themistor flake supported by a substrate. The IR thermometer further comprises a processing circuit which analyzes the response to predict the steady-state response of the at least one IR sensing element and temperature of the object. In one embodiment, the processing circuit may obtain two or more responses separated by a predetermined period of time to predict temperature of the object. The processing circuit may also associate reference data in its prediction algorithm.

Abstract: A blackbody cavity having two types of wall surfaces wherein a first type has high emissivity and a second type has low emissivity. The low emissivity wall surface has an aperture from where the infrared radiation escapes the cavity, and is preferably shaped to minimize the escape through the aperture of radiation emanated directly from the low emissivity wall itself. The combination of high and low emissivity wall surfaces allows the blackbody to reduce the influence of the environmental temperature while maintaining emissivity approaching unity.
