A sensor assembly for imaging passive infrared (IR) scenes and active laser radar (LADAR) scenes and for generating multi-dimension image data sets, and a method for same. A two-dimensional semiconductor imager sensitive to both passive IR radiation and active LADAR radiation when used in conjunction with subsequent signal processing creates a two-dimension passive image data set and a three-dimension active image data set with common x and y coordinates. The passive image data set is collected substantially proximate in time with the active image data set. The two image data sets are combined to form a multi-dimension image data set with the surface of three-dimensional objects indicating heat emission. The sensor assembly applies to burst illumination LADARs operating at a variety of wavelengths and passive IR detection in the middle wavelength IR (MWIR) or long wavelength IR (LWIR).

[ What is claimed is:] [1.]1. A sensor assembly for detecting a scene which emits passive radiation and reflects active radiation, the sensor assembly comprising:an imager for imaging the scene, said imager for producing a passive image signal based upon passive scene radiation and an active image signal based upon active scene radiation;a passive signal channel for integrating the passive image signal for producing a passive image data set from said integrated passive image signal; andan active signal channel for sampling the active image signal at predetermined times for producing an active image data set from said sampled active image signal, said active image data set comprising horizontal, vertical, and range data.
