INSTALLATION TO MEASURE ANGULAR FIELD AND TO MONITOR STEP SIZE OF TEST-OBJECT MIRA LINES Russian patent published in 2014 - IPC G01M11/02 G03B43/00 H04N17/00 

FIELD: measurement equipment.

SUBSTANCE: installation comprises a collimator with a test-object, a monitored item and a measuring unit. The test-object is made as a cross hair and rigidly fixed in the focal plane of the collimator. The monitored item is made as television or thermal imaging one, its radiation detector is set in the focal plane of the lens of the monitored item. A flat mirror able of rotating around the vertical axis is installed between the collimator and the monitored item. The collimator output via the flat mirror is connected to the monitored item lens. The measuring unit comprises a panel for synchronisation and formation of line illumination pulse and two margin pulses, a double-beam oscillograph and a video monitor. The monitored item output is connected to the input of the first channel in the double-beam oscillograph and to the input of the panel for synchronisation and formation of line illumination pulse and two margin pulses, while the first output of the latter is connected to the video monitor input. The second output of the said panel is connected to the input of the second channel in the double-beam oscillograph.

EFFECT: improved reliability of the obtained results, increased information value and monitoring accuracy, possibility to monitor and define test-object parameters in the form of miras with vertical and horizontal lines.
