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

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
Key words: pulse co2 laser; long-wave infrared detector; HgCdTe ;disturb threshold; damage threshold
