Automated testing of methods that reproduce angular quantities on the basis of a ring laser

Dynamic angle measurement by means of a ring laser

“…According to ( 6) and ( 8), the procedure of angle measurement during revolutions of the platfor m may be writte n as p (9) where is the number of the angle converter intervals in p and the denominator terms of (9) represent the determination of the scale factor number p at every revolution.…”

“…This commercial system, GS-1L, is employed in the countries of the former Soviet Union and elsewhere, for exam ple at the Slovakian Metrology Institute (SM Â U, Bratislav a) [7], as a standard for the plane angle unit. Further developm ent of the RL goniometer was carried out by some companies and universities [8,9], particularly at the St Petersburg Electrotechnical University (SPEU) where such systems were developed, for example, for producing circular scales and for noncontact measurements of an object' s angular position [10,11]. The developm ents undertaken by the SPEU ultim ately gave rise to the commercial laser goniometer system EUP-1L.…”
