Original Abstract

The paper is focused on realization and verification of a light-flickermeter simulating response of the average observer on disturbing light flicker under specific conditions. The design of the light-flickermeter is based on digitized the standard UIE/IEC flickermeter measuring scheme where the measuring chain does not include model of the reference incandescent bulb. It means that this type of flickermeter output is expected to be independent on a light source type producing light flicker. The developed instrument evaluates measured luminous flux fluctuation utilizing appropriate hardware and signal processing. The light is sensed by a photodiode with build-in transimpedance amplifier and photopic correction light-filter. The amplifier RC feedback allows control of its transfer function gain and bandwidth. Then the subsequent signal processing is based on NI PXI (cDAQ or cRIO) platform and virtual instrumentation in LabView. For purpose of various type flickermeters verification and calibration, a test system composed of a SW designed in LabView, NI PXI arbitrary waveform generation board, a power amplifier and a lamp placed in a test chamber, allowing generation of testing signals, has been developed. And finally, results of the light-flickermeter advanced performance analysis are shown and discussed.
