METHOD OF CHECKING PARALLELISM OF SIGHT AXES OF MULTISPECTRAL SYSTEMS Russian patent published in 2012 - IPC G01M11/00 G02B23/10 G01C3/08 

FIELD: physics.

SUBSTANCE: method involves formation of collimated light flux from a reference mark, direction of said flux into optical channels of the electro-optical modules of the system using reflecting optical elements and formation of an aiming mark where the image of the reference mark is located. The reference mark used is the field diaphragm of the receiving module of a laser range-finder. The reference mark is illuminated with a wide-spectrum light source. The image of the diaphragm is transmitted using the mirror lens of the receiving module of the laser range-finder, trippel-prisms and input lenses the electro-optical modules of the system into their focal planes. In each module, coordinates of the centre of the image of the diaphragm are determined and electronic aiming marks are formed in accordance with the obtained coordinates.

EFFECT: high accuracy of aligning multichannel multispectral systems and maximum simplification of the design of the alignment system and shorter time for alignment.
