A Study on Dual Spectral Range IR Detection

Several significant problems on IR radiation, laser ranging and atmospheric visibility in dual spectral range IR detection are studied and analysed.The dual spectral range IR dectection spstem, where a double layer detector is used,can measure are the radiation inbeity, with simultaneous compensations on environmental and atmospheric influences.The system is very sensitive in the detection of IR radiation characteristics of moving objects at a distance under different environments.
