<title>Optical power and irradiance microprocessor meter for fiber optic sensors and networks testing</title>

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 1 nW to 2 mW and an irradiance of light from 50 nW/cm2 to 150 mW/cm2 (with accuracy 0.2%) including sensor's and spectral responsively characteristic. It's built for measuring fiber optic systems, mainly for examination and testing of the optoelectronic 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 fiber optic sensors and networks.© (1999) COPYRIGHT SPIE--The Interna…
