Systems and methods for heliostat mirror tracking

Abstract

An aspect of the present disclosure relates to methods and systems for enhancing the flux distribution on a heliostat receiver target. A plurality of mirrors in a heliostat array are caused to vibrate at respective different frequencies. One or more images are captured of the total flux on a heliostat receiver target. Fast Fourier Transforms are performed in real time with respect to the one or more images of the total flux on the heliostat receiver target to obtain frequency domain information. A real time determination is made of the flux contribution by a given individual mirror using the frequency domain information. A desired total flux distribution is determined. One or more of the plurality of mirrors in the heliostat array are caused to be oriented to obtain the desired total flux.
