Analysis of working range in IR camera measurement

Parameters of infrared cameras play an important role in the application of IR cameras. Most of these parameters' testing principles are based on the measurement of radiation. In order to make measurement accurately, factors such as distant from the test camera to the apparatus, optics index of reflection of measurement unit and atmospheric transmission must be evaluated carefully. By means of the analysis of radiation energy, the concept of "working range" of a double-blackbody parameters measurement unit and its mathematics model are proposed. The distribution of radiation is simulated.
