Zusammenfassung:•Programmable light source (PLS) produces light of virtually any waveform.•PLS is either a stand-alone function generator or an integrated computerized unit.•Any electrically controlled light source may be used, depending on required speed. Programmable light source is an opto-electronic device, producing modulation of the intensity of light of any, physically permitted, shape. It is composed of an electrically controlled light source connected in a negative feedback to a linear photodetector, and programmable electronic signal generator that drives the light source. Theory of operation, design guidelines, and experimental results are presented.
