Abstract: An imaging arrangement combines a thermal imager with a laser imager to enable several correlated pictures to be produced which show different properties of the same field of view. A common scanning device is used to scan each pixel in the field of view in a raster-like pattern, and for each pixel data can be derived representing thermal content, range, optical reflectivity and velocity. The last three properties are obtained by coupling an optical interferometer to the scanning device which generates the picture representing the thermal content.
