TWO COLOR LINE SCANNING PYROMETER

摘要

A scanning radiation sensor provides a dual spectral infrared measurement scheme that is capable of providing contactless temperature measurements from a plurality of points along a scan line of a target surface area without knowing the emissivity of the target surface. The sensor is capable of correcting for changes in the emissivity of the target due to varying surface conditions. The dual spectral line scanning infrared sensor determines the radiation from each of a plurality of spots along a scan line on a target, and produces an average radiation from the plurality of spots, and converts the average radiation to a representation of temperature of the target.
