4. Chromatic flicker perception modeling in flickermeters

   Visible light variation may leads to disturbance of human’s visual perception. The origin of such negative effect is in the eye anatomy and physiology. The major influence on the flickering light perception can be found in eye viewing field, photoreceptors (cones of three types and rods) and their distribution at retina as a part of eye anatomy and in eye adaptation mechanisms like pupil, photo-chemical and neural adaptation (response) to luminous variations (including the photoreceptors spectral luminous efficiency) as a part of eye physiology. The human eye can be seen as specialized luminance multi-detector where the stimulation contrast is as important as radiant density. There are differentiated three types of flicker: temporal, spatial and chromatic. All of these flickers are joyless and may involve many psychological interactions. In artificially illuminated areas, lamps light variations due to variations in supply voltage may also lead to flicker perception. Such lamp possibly will produce light with time-varying radiant flux and its spectral distribution. The lamps flickering is produced by a voltage Phase Modulation (PM), mainly by Phase Jumps (PJ) and by Interharmonic Voltages (IH) superimposed on a voltage waveform. Thesis is focused on the voltage fluctuation to lamps time-varying radiant flux and its spectral distribution fluctuation transfer analysis and on the utilization of the analysis results for development and realization of an objective flickermeter having response to both the temporal luminance and chromatic flicker. The thesis aim is the realization of the new flickermeter types implemented in LabVIEW, with the experimental verification. The thesis covers theoretical-analytical, developmental and also practical-experimental part of study. More information: drapela@feec.vutbr.cz.
