最近文献[1]报导了红外探测器的一项重要进展,可用一根n型碲镉汞细丝来实现串扫或串并扫热成像系统的探测与延时积分功能。这种探测器的名称SPRITE系元件内的信号处理一词的缩写。在SPRITE探测元件中,为图像沿细丝移动所选择的速度,与外加偏置场影响下光激发载流子沿细丝的漂移速度相对应。这样一来, Recent literature [1] has reported an important advance in infrared detectors that an n-type HgCdTe filament can be used to detect and delay integration of a tandem or tandem thermal imaging system. The name of this detector SPRITE Department of signal processing in the acronym. In SPRITE detection elements, the velocity chosen for the image movement along the filament corresponds to the drift velocity of the photoexcited carriers along the filament under the influence of an applied bias field. Thus,
