Abstract

A method for light-to-frequency conversion comprises the steps of illuminating a photodiode by a light source, generating a photocurrent by means of the photodiode, converting the photocurrent into a digital comparator output signal depending on a first clock signal, generating a first count comprising an integer number of counts, where the generation of the first count depends on the first clock signal, generating a second count which relates to the time interval between at least two counts of the first count, and determining the frequency of a repeating pattern in the intensity of electromagnetic radiation emitted by the light source and detected by the photodiode from the first count and the second count. Furthermore, a light-to-frequency converter arrangement is provided.
