Test of 1550nm Infrared Laser Illuminator for Through-Windshield Observation

In this test, a 1550nm infrared laser lighting moudule was used in conjunction with an industrial infrared camera to evaluate the through-windshield observation performance under natural daylight conditions. 

The test also compared the results with and without a polarizing filter attached to the camera. The test results show that the through-windshield observation effect with the polarizing filter is significantly better, delivering clear and detailed monitoring images.
