Embodiment Construction
[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] The basic principle and idea of this application are: the upper surface of the detector window is a microlens array, which has a converging effect on light and can improve the utilization rate of light; the lower surface of the window is a filter for both visible light color imaging and infrared imaging, which can Day and night; the pixel unit has two working modes, R+IR (red light + infrared light), G+IR (green light + infrared light) and B+IR (blue light + infrared light) three sub-pixel units during daytime work The obtained detection signal can be subtracted from the detection signal part obtained by the IR (infrared light) sub-pixel unit, so as to ensure that the detection signals of the R+IR, G+IR, and B+IR sub-pixel units show true color; when working at night, the visible light signal is very weak , the four filters can trans...
