Altering Integral Time Method in Temperature Measurement Using Mid-Wavelength Infrared Imaging System

Abstract:

Mid-wavelength infrared imager is widely used in the fields of security and detection with its unique band imaging characteristics, and it needs related studies of radiance calibration as to be used accurately and effectively. With the linear property of the infrared imager, which is the relationship between the input radiance and the output gray of the imager, the pupil radiance can be measured. Moreover, the surface temperature of the target in the image can be acquired combined with the surface characteristics. However, there is every possibility that the temperatures of the target change so much along with the day that it cannot be measured with just one linear field of the imager. This paper proposed an altering integral time method to measure temperature, which adapts to large temperature variations.
