The infrared imaging sensor can detect the invisible thermal radiation, while the visible light sensor can detect the target through the absorbing of the visible light band electromagnetic wave reflected by the target. 红外成像传感器检测目标发出的不可见热辐射,而可见光成像传感器则通过吸收目标反射的可见光波段电磁波来实现对目标的探测。
Infrared radiation is invisible radiation It is electromagnetic wave lying between visible light and microwave in nature. 红外辐射是一种不可见的辐射,它的本质是介于可见光和微波之间的电磁波。
