Dual-mirror transmitter and receiver combination is used with laser multispectral imaging system carried by low fly aircraft. Device can be arranged to reduce laser light backscatter which creates false light levels in recorded image and compensates for scanning phase delay between transmitter and receiver.
The development of an experimental airborne multispectral scanner to provide both active (laser illuminated) and passive (solar illuminated) data from a commonly registered surface scene is discussed. The system was constructed according to specifications derived in an initial programs design study. The system was installed in an aircraft and test flown to produce illustrative active and passive multi-spectral imagery. However, data was not collected nor analyzed for any specific application.
