摘要:
根据PV探测器的开路输出公式,建立了涵盖长波、中波、短波的HgCdTe探测器响应模型。模型仿真发现探测器被激光辐照后产生的温升将降低探测器的输出,探测器被激光直接照射后会立即产生饱和输出。综合实际应用提出了探测器软损伤的判断门限。
Abstract:
Based on the open-circuit output function of a photovoltaic (PV) detector, the response model of a HgCdTe detector that is operable in the long-wave, medium-wave, and short-wave bands is established. Simulation results show that the temperature rise generated by laser irradiation reduces the output of the detector, and the detector produces a saturated output immediately upon direct irradiation by the laser. Based on practical applications, the threshold of soft damage to the detector is proposed.
