Optical power and irradiance microprocessor meter for fibre optic sensors and networks testing

In this paper are presented the optical power and irradiance meter with "an intelligent opto sensor" and the microprocessor measurement system. A designed and programmed microprocessor unit allows to measure a light power from I nW to 2 mW and an irradiance of light from 50 nW/cm(2) to 150 mW/cm(2) (with accuracy 0.2 %) including sensor's and spectral res-pensively characteristic. It's built for measuring fibre optic systems, mainly for examination and testing of the optoeletronic sensor's structure (relatively small surface of the light detectors comparing to the partition of measured value) and it's an ideal detector for the fibre optic (FO) sensors and networks.
