Abstract

A system for virtual aligning of optical axes in a sight comprising a laser (1) having a first optical axis (2), a video camera (3) having a second optical axis (4), and an IR camera (6) having a third optical axis (7), the optical axes (3, 4, 7) being essentially parallel to each other, where a laser beam emitted from the laser (1) along its first optical axis (2) is caused by means of a prism (10) to be reflected 180 DEG and to be projected onto a sensor (5) in the video camera (3) so that a virtual aligning of the first (2) and second (4) optical axes can be executed by image processing, where a light source (15) is made send a light beam to a beam splitter (14) located in the second optical axis (4), whereby the light beam is deflected out through the video camera's (3) objective (13) and is reflected by a reflector into the video camera's (3) sensor, (5) permitting a virtual aligning of the light beam in relation to the first optical axis (2) to be effected, and where the reflector and prism (10) are moved aside and a mirror (20) is placed in the path of both the video camera's (3) optical axis (4) and the IR' camera's optical axis (7) so that the light beam from the light source (15) is reflected by the mirror (20) into the video camera's (3) sensor (5), and the IR camera's (6) IR beam is reflected by the mirror (20) whereby, since the geometry of the mirror (20) is known, a virtual alignment of the IR camera's (6) optical axis (7) with the light beam and thus with the first optical axis (2) is performed by mean of image processing.
