A relatively compact, lightweight, and programmable spectropolarimetric imager was used to collect spectral and polarization data from various objects and backgrounds, both in the laboratory and in field tests. This imager uses a tellurium dioxide (TeO2) acousto-optic tunable filter and a liquid-crystal retardation plate with a CCD camera. The spectral images were collected 450-1000 nm at 10- or 20-nm intervals at two or four polarization settings for each spectral interval. We analyzed a portion of these data to assess the effectiveness of this system for object detection. We present our measurements and discuss the analysis results.
在实验室和现场测试中，使用了一种相对紧凑、轻便且可编程的光谱偏振成像仪，从各种物体和背景中收集光谱和偏振数据。该成像仪使用二氧化碲（TeO2）声光可调滤波器和带有电荷耦合器件（CCD）相机的液晶延迟板。光谱图像在450 - 1000纳米范围内，以10纳米或20纳米的间隔，在每个光谱间隔的两个或四个偏振设置下进行采集。我们分析了这些数据的一部分，以评估该系统在目标检测方面的有效性。我们展示了我们的测量结果并讨论了分析结果。
