Implementation and Preliminary Verification of an Alternative Flicker Observer Model

This paper studies an algorithm for determining the flicker severity of luminous flux produced by artificial lighting systems. The algorithm is defined in time domain and constitutes an alternative to the widely used flicker observer model (light flickermeter) known as IEC Technical Report 61547-1:2015. The paper describes and discusses a few aspects related to the implementation of the algorithm. An alternative filter definition is suggested. Finally, the algorithm is compared in simulation with the standard observer model using several properly chosen tests.
