ABSTRACT:
A system and a method of designing and mechanical packaging of a fully integrated multifunctional multispectral miniaturized sight assembly to allow its use on hand-held man-portable units. All the subsystems of the compact sight assembly, namely, a direct view day subsystem, a CCD-based visible TV subsystem, a staring IR night subsystem, an eyesafe laser rangefinding subsystem and a display subsystem for viewing the output of the TV or IR subsystem, are aligned and use a single telescope and eyepiece in order to decrease the size of the assembly. In addition, each sight assembly subsystem operates in a first and a second field of view, preferably in a narrow field of view and a wide field of view, with wavelengths from 0.45 .mu.m to 12 .mu.m, thereby creating a very small but highly powerful sight assembly.
