Compressed sensing for PV measurements

To enable the projection of patterns produced by a computer program we used an active Microelectromechanical system (MEMS) mirror array, such as those present in many computer projectors used in meeting rooms.

This consists of an array of tiny mirrors which can be individually addressed and switched into one of two positions. This allows each of these mirror 'pixel' to project light onto the photovoltaic or to dump it elsewhere. In this way we can produce any desired pattern.
