FIELD: instrument making.
SUBSTANCE: autocollimator contains photoelectronic autocollimating channel, electronic equipment for formation of digital information and personal computer. Autocollimating channel consists of lens, cube-prism, set of photoreceivers, cross-shaped autocollimating mark and light source. Photoreceivers are one-line image sensors. Sizes of cross-shaped autocollimating mark, parameters of lens, location and the number of photoreceivers and their parameters, namely sizes of their light-sensitive surfaces are chosen from condition of bringing the image of cross-shaped autocollimating mark onto a pair of orthogonal photoreceivers at any location of mirror in the range of measured angles.
EFFECT: improving pick-up frequency of readings to tens of kilohertz.
