Abstract

Design of means for measuring optical radiation power of small levels (below i05 W) has come into an active phase in the '80s thanks to a fast development of fiber optical transmission systems (FOTS) . Atfirst, all manufacturers producing this kind of measurement means have calibrated them at their own laboratory facilities. This has led to a good deal of discrepancy in measurement results which became evident in the very first comparison studies' .Toavoid the discrepancy that could lead to dramatic consequences up to a total mismatch of fiber optical systems, special neasurement standards have been suggested and appropriate hardware has been designed to reproduce and transmit the power unit. The transmission of the power unit may be affected in most different ways. Techniques used initially for this purpose were traditional for non coherent radiometry. In our country, the transmission of the power unit is carried out by a multistage technique crowned by a primary State Standard for the average power of laser radiation of medium level. The leading world companies in the USA, Germany and Japan obtain the power unit value from primary standards of radiation of small levels.
