碲镉汞已有十五年历史,目前已成为夜视技术中主要的红外探测器材料。已经为美国三军并可能为北大西洋条约组织所采用的红外前视装置通用组件,就包括了180元光导碲镉汞探测器组件。一、多光谱碲镉汞可以选择截止波长,做成多光谱器件,即在焦平面上做有几层碲镉汞,每一层都起被动滤光的作用;顶层在其截止波长范围内吸收辐射能,把专吸收的能量透射到
HgCdTe has been fifteen years old and has become the major infrared detector material in night vision technology. The common component of infrared front-view devices already used by the U.S. Armed Forces and possibly the North Atlantic Treaty Organization includes the 180-element light guide cadmium telluride detector module. First, the multi-spectral HgCdTe can choose the cutoff wavelength, made of multi-spectral devices, that is, in the focal plane do have several layers of HgCdTe, each layer play a role of passive filter; top layer in its cut-off wavelength range absorption Radiation energy, the absorption of energy absorbed through to
