Flicker Severity Threshold Measurements

The IEC flicker observer model, or light flickermeter, is an algorithm whose purpose is to assess the severity of flicker produced by artificial lighting. Historically, it was developed by extraction from the voltage flickermeter, and it is thus based on experiments with incandescent lamps. This paper is one in a series of papers focused on verifying the light flickermeter performance for LED light sources. Flicker visibility threshold is measured in conditions taking into account peripheral vision. The data are then compared to the thresholds indicated by the light flickermeter.
