摘　　要：低温目标红外辐射的灵敏探测和成像在航天和深空探测中具有重要的应用价值.300 K以下低温目标的辐射强度很弱,辐射特征波长位于中远红外区.阻挡杂质带红外探测器是中远红外探测器中重要的一员,具有覆盖波段宽、灵敏度高、暗电流低、抗辐射性能高等优点,能够胜任空间技术和天文探测在中远红外波段探测的苛刻要求.本文以红外天文探测对红外探测器的应用需求作为出发点,主要就国内外红外天文学、红外天文探测器发展概况,阻挡杂质带红外探测器发展历史及其材料、器件结构等方面做了简要综述,并简明扼要地介绍了阻挡杂质带探测器的器件物理模型.The imaging and ultra-sensitive detection of infrared radiation for cryogenic target in space and deep space exploration have significant application value. The radiation intensity of the target below 300 K is quite faint, whose corresponding characteristic radiation wavelength is very long. Blocked impurity band （BIB） detectors are one of the most important members in far-infrared detectors, with advantages of wide spectrum coverage, high sensitivity, low dark current, good resistance to cosmic particle radiation and capable of meeting the stringent requirements of astronomical exploration in far-infrared waveband. Getting start from the demands of infrared astronomical detection, this article represents the current status and progress on infrared astronomy, infrared detectors for astronomy and the blocked impurity band detectors. Additionally, the device structure and simplified physical model of BIB detectors are well-covered.
