infrared ccd camera
Why infrared signal can be detected by CCD camera?
Why does it look white?
CCDs are sensitive in nature to approximately 1000 nm (nanometers), while the human eye can not see much beyond 760 nm. CCD cameras have IR filters block, but some of them still leaves a considerable amount of infrared in. A quick test whether your camera is infrared sensitive to your TV remote and a button on the pressure point. If it is sensitive, you see the IR LED light the LCD viewer. A CCD camera uses red, green and blue filtered pixels to a color image. Infrared appears white because apparently all this pixel filters let through IR.
