Abstract: A method for determining an angle of incidence of periodic optical signals is provided. The method includes detecting whether the periodic optical signals are present; generating a pulsed output when the periodic optical signals are present, the pulsed output corresponding to peaks in the periodic optical signals; predicting a timing of the periodic optical signals from the pulsed output; controlling a gated detector array to take a first reading and a second reading of the periodic optical signals based upon the timing, the first reading being out of phase with the timing and the second reading being in phase with the timing; and generating the angle of incidence by filtering the first reading from the second reading.
