  • Device for monitoring of alignment of two optical paths and laser designation system equipped with such a monitoring device
    Patent number: 5251003
    Abstract: The invention relates to a device for monitoring of alignment of two optical paths, a laser aiming path and an infrared imaging path.The monitoring device according to the invention is composed of two half-housings, and of a cassette containing a polyimide film (11) and means of advancing of this film.The housing acts as a cube corner in order to re-emit, from an incident laser beam (FL) to an infrared beam (FI) which is collimated and strictly parallel or coincident with the incident beam (FL) by heating of a an optical system for focusing/collimation (15 to 21). The position of the hot point visually displayed on the infrared detector makes it possible to measure the alignment offset of the two paths.Application to systems for target designation by laser guidance with two separate or partially coincident optical paths.
