A Temperature Compensation and Calibration Method for Thermal Infrared Array Sensor

A temperature compensation and calibration method of the thermal infrared radiometer array sensor were introduced to improve the measurement accuracy. A maximum temperature calibration model were established based on the matrix IR temperature sensor, and a distance uniform method were introduced in this paper. By using the method, measurement error can be calibrated without the limitation of the angle and distance of the IR array sensor. Test results showed that this method can reduce the influences of the angle or distance of the measurement, and improve the accuracy.
