An infrared integration method to discover the object of high temperature i
n the video image is put forward by analyzing not only the radiation spectr
um distribution of the scenery and target, but also the CCD (Charge Coupled
Device) spectral response theoretically. LCLV (Liquid Crystal Light Valve)
is used with CCD ingeniously, so that the LCLV-CCD can be used for both no
rmal monitoring and discovering the high temperature object in the image.
