Optical system with automatic mixing of daylight and thermal vision digital video signals

摘要

An optical sight system that comprises a combination of a thermal scope with a CCD visible-range attachment connectable to the thermal scope with a quick-release connector. The system is equipped with a device for automatic interposition of the digital visible image of the CCD visible-range attachment onto the digital thermographic image when the attachment is electrically and mechanically connected to the thermal scope. The CCD is a light-weight device which does not have screen and which is easily attached to the thermal scope by means of a quick-release connection unit. Both digital images are observed on the screen of the thermal-scope display.
