摘　　要：单一探测器实现多维度信息获取是光电探测未来的发展方向。针对目标探测中能量和偏振信息不能兼顾的问题,提出了一种同时具有偏振-微光功能的像元阵列结构。通过引入白光通道和精简偏振通道,可在EMCCD器件上实现偏振和微光探测的一体化集成。实验结果表明,在微光条件下,探测器高灵敏性能被保持,低照度下的成像质量几乎不衰减;偏振模式下,白光通道和两个偏振角度使探测器能够获得足够的偏振信息,实现对目标的偏振探测。该方法实现了高灵敏度成像探测和偏振信息探测的同步获取,是一种通过算法处理就能够实现探测模式可重构的新方法。Multi-dimensional information acquisition by single detector is the future direction of photoelectric detection.Aiming at the problem that the energy and the polarization information could not be considered in target detection,a new pixel array structure with polarization-low level light integrated function was proposed.The integration of polarization and low level light detection was realized in electronic multiplying charge coupled device(EMCCD)by introducing the white light channel and the reduced polarization channel.The experimental results show that under the low level light condition,the high sensitivity of the new detector is held,and the imaging quality at low illumination is almost not decay.In polarization mode,the white light channel and two polarization angle enable the detector to obtain enough polarization information,so as to realize the polarization detection of the target.Synchronous acquisition of high sensitivity imaging detection and polarization information detection by this method is realized,and the reconstruction of the detection mode can be realized by the algorithm processing.
