Abstract
The invention relates to a system and method for performing a laser Doppler flowmetry, LDF, measurement. The system comprises a coherent light source, a photodetector and one or more processors. The photodetector generates an output signal. The processor(s) determines a selected frequency range for computing an LDF signal. A spectrum of the photodetector output signal is computed for a series of time intervals, thereby obtaining a series of spectra. A measure of the amount of physiological information in the spectra is computed for a number of different frequencies. The selected frequency range is determined as the range of frequencies for which the computed measure of amount of physiological information fulfills a predetermined criterion. The processor(s) compute an LDF signal using the selected frequency range, and output the LDF signal.
