METHOD OF MEASUREMENT OF PARAMETERS OF OPTICAL SYSTEMS Russian patent published in 2008 - IPC G01M11/02 

FIELD: measuring technique.

SUBSTANCE: method can be used for measurement of focal length, radius of diaphragm and parameters of photosensitive area of array photoreceiver of image of optical systems of electro-optical detector during development and testing of technical vision systems. According to method of measurement of focal length of optical system of electro-optical detector, array image receiver of electro-optical system is disposed at distance being coincident with focal length f of optical system of electro-optical system. Optical system of electro-optical system is focused to infinity. Test point object is placed onto optical axis and it is shifted along optical axis for known distances c₁, c₂, c₃. Radius of circle at image is measured automatically for any position of point object. After that value of focal length of optical system of electro-optical system is calculated as well as sizes of photosensitive area of array photoreceiver of electro-optical system and value of radius of diaphragm, which restricts path of end beam through optical system of electro-optical system.

EFFECT: improved precision of measurement; reduced complexity of practical realization.
