Abstract
Abstract A multispectral laser camera made up of a plurality of energy producing means which scan a target area. The resultant reflected light off the target produces a true color image of the target after being processed through a series of photomultiplier tubes, amplifiers and modulators. By selectively varying the connections between the above elements a false color image of the scanned target may also be produced. This false color image overcomes the difficulties in detecting camouflaged targets.
