Abstract

An optical system consisting of a basic day-vision optical device, such as an optical sight, and a digital optical attachment unit, such as a CCD module, a thermovisor, a range finder, or the like. A distinguishing feature of the system is the optical attachment unit which does not have an eyepiece and contains a power supply unit for the basic day-vision optical device. On the other hand, the basic day-vision optical device does not have a power supply unit but among other things contains a beam splitter and an electronic microdisplay. When the digital optical attachment unit is attached to the basic day-vision optical device and electrically connected to the latter, the electronic microdisplay receives a target image from the digital attachment unit and through the beam splitter a target and reticle image obtained by the basic day-vision device. As a result, a viewer can see an enhanced fused image of both image components reproduced on the electronic microdisplay.
