Research on the Array Type Infrared Radiation Thermometer

In recent years, infrared temperature-measuring attracted more and more attention from home and abroad. Infrared temperature-measuring is non-contact and does not destroy the temperature distribution of the measured target object. At present, infrared radiation thermometer (point thermometer) and thermal infrared imager are wildly used. They both have advantages and disadvantages. The array type infrared radiation thermometer discussed in this paper contains the advantages of IR thermometer and thermal infrared imager and could measure the multi-point of the target’s surface simultaneously and accurately. Its basic principle is to obtain array processing to the infrared detector, simultaneously measure the multi-point temperature of the objects, take the measured object as a benchmark to calibrate infrared radiation thermometer so as to solve the problem of radiation rate fixed difficulties and improve accuracy of radiation temperature measurement.
