COMPARATOR FOR DEFINITION OF CYCLICAL ERROR OF HIGH-PRECISION LIGHT RANGE FINDER AND ELECTRONIC TACHOMETER

摘要

FIELD: invention refers to arrangements for measuring of distance and serves for definition of cyclical error of high-precision light range finders and electronic tachometers. ^ SUBSTANCE: arrangement has vacuum chamber with glass window and placed in it carriage with reference reading arrangement and possibility of longitudinal displacement on which there is installed angular reflector optically connected with checked light range finder. Direction of displacements of carriage coincides with direction of measuring line. ^ EFFECT: increases efficiency of process of measuring and reduces errors of measurements at checking high-precision light range finders and electronic tachometers. ^ 2 cl, 1 dwg
