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.

The invention claimed is: 1. An imaging arrangement including: a scanning device for sequentially viewing different elements of a scene; thermal sensing means coupled to said scanning device for forming a two-dimensional image of scene-emitted thermal radiation; an optical source arranged to generate a frequency modulated laser beam for illuminating the scene via the scanning device; optical sensing means coupled to said scanning device for extracting data from the light reflected by the scene in response to the illumination by said optical source; and narrow band filter means for separating laser light reflected from the scene from thermal radiation emitted by the scene, said narrow band filter means being positioned between the optical source and the scanning device and being a partially transmitting, partially reflecting device.
