N2 - Three perception experiments were conducted to develop a measure for predicting the visibility of the stroboscopic effect occurring in temporally modulated light systems. In the first experiment, different methodologies were evaluated for their measurement error. In the second experiment, the visibilities of the stroboscopic effect for square wave and sine wave light modulations were measured and the results were found to be consistent with previous findings for flicker perception. In the third experiment, specifically crafted, complex waveforms were used to test the theory of frequency summation. Based on the results of these three experiments, a new measure for the visibility of the stroboscopic effect was developed, consisting of a summation of the energy in all frequency components, normalized for human sensitivity
