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.
