| Abstract: | A detecting module for measuring power density of mid-infrared laser is developed using room temperature HgCdTe photoconductor detector. The module is consisted of optic filter attenuator, HgCdTe detector, amplifier, analog to digital converter, and signal processor. The temperature characters of the HgCdTe detector are analysed, and the responsivity self-adjusting model of detector with temperature is established. The module is suitable for power density measuring of mid-infrared laser when the working temperature is －30~40 ℃, with measurement uncertainty less than 20%． |
