Paper Abstract

The new method of multireflected autocollimation allows to perform angle measurements with greater accuracy than the accuracy of the measuring device itself (theodolite, autocollimators, etc.). The article contents are: description of the method's principle and its theoretical analysis; photograph of experimental angular measurements with theodolite T16 - using this method, an accuracy of + 0°0'5" was achieved by direct reading (less than 000'1" by estimated reading); photograph of the set-up which was used for reception tests of "Microcontrole" Mirror Mount SL20A; possible method application principle layout for increasing measurement accuracy of devices and for calibration of angular measurement devices.
