DEVICE FOR CONTROL OF LASER CONTROL CHANNEL PARAMETERS Russian patent published in 2009 - IPC F41G3/32 G02B27/62 F41G7/26 

FIELD: physics, optics.

SUBSTANCE: device comprises lens, mesh with transparent diaphragm and check marks on its working surface, which is installed with the possibility of displacement in direction that is perpendicular to lens axis, system for illumination of mesh check marks, the first photodetector device, which is optically connected to mesh, and electronic device for control, processing and generation of measurement information. The following components are introduced and installed on optical axis of lens: spectrum divider, attenuator of laser radiation, the second photodetector device, and also electric drive for mesh displacement, detector of mesh position and video observation device. The first and second inlets of electronic device are connected to the outlets of the first and second photodetector devices, the third inlet - to detector of mesh position, the fourth inlet has possibility of connection to outlet, and the first outlet - to the inlet of laser control channel of controlled device, the second outlet - to electric drive of mesh displacement, and the third outlet - to video observation device.

EFFECT: expansion of functional resources by provision of control over time cyclogram of laser control channel operation and power of laser radiation, improved efficiency and accuracy of control by automation of performed operations and processing of measurement results.
