Abstract

The invention relates to an infrared polarization imaging measuring device based on a rotating polarizer. The device comprises an infrared optical lens, a multi-directional polarizing unit, an infrared focal plane detector and a control unit. The infrared optical lens adjusts the polarized light of a target scene to acquire a detecting beam. The multi-directional polarizing unit acquires polarizedbeams with different polarizing directions by changing the polarizing direction of the detecting beam. The infrared focal plane detector images the polarized beams of different polarizing directionsto acquire the infrared intensity images of the polarized beams of different polarizing directions and output the images. The control unit is used to control the multi-directional polarizing unit to sequentially change the polarizing direction, so that the infrared focal plane detector can acquire the infrared intensity images of the polarized beams of different polarizing directions, which are corresponding to the sequentially changing polarization direction, at a predetermined frame rate. The device provided by the invention can be used to measure the moving or changing target scene.

Description

technical field [0001] The invention relates to the technical field of infrared polarization imaging measurement, in particular to an infrared polarization imaging measurement device based on a rotating polarizer. Background technique [0002] Polarization imaging detection is a new type of target detection technology. Compared with traditional photoelectric imaging detection technology, it can not only obtain the radiation intensity information of the target scene, but also obtain polarization parameters such as degree of polarization, polarization angle, and polarization ellipticity, and increase the detection rate. The dimension of target scene information is of great significance to improve target detection and recognition. [0003] With the increasing demand for infrared polarization imaging detection applications, infrared polarization imaging methods are also continuously developing. At present, the more common infrared polarization imaging technologies are mainly div...
