DIGITAL COLLIMATOR Russian patent published in 2018 - IPC G02B27/30 H04N5/74 G02B26/08 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the field of optoelectronic instrumentation. Digital collimator includes an optically coupled illuminator, test object, lens, beam splitter and transmitting lens. Digital micromirror device is used as a test object. Beam splitter and the transmitting lens are located between the test object and the lens, wherein the illuminator is optically coupled to the test object by means of said beam splitter, which is located at an angle to the optical axis of the digital collimator in such a way that the light flux reflected from the rotated micromirrors of the digital micromirror device propagates along the optical axis of the digital collimator or to the side.

EFFECT: technical result consists in simplifying the design and reducing the duration of the control and adjustment operations of the digital collimator.
