用10.6um脈沖CO2激光遠距離輻照長波紅外HgCdTe光電探測器，進行了干擾與破壞閾值的實驗研究，通過改變激光輻照探測器上的能量密度直至探測器達到干擾、損傷，得出了HgCdTe探測器的干擾與損傷閾值；利用二維半無限大模型計算了激光干擾及損傷探測器的閾值，與實驗值相近，結(jié)果表明3km處要達到干擾必須達到10-6J數(shù)量級。

Abstract: Under the remote irradiation of the pulse10.6um co2laser at various energy density, the output signal of long-wave infrared HgCdTe detectors has been studied ,and the disturb and damage thresholds are determined．In the mean time，disturb and damage thresholds of detector irradiated by laser were calculated by using two-dimensional semi-infinite solid mode1.it close to the experiment result，which should reach 10-6J
