Zusammenfassung:A method for applying power in a plurality of pulses to the projection source to control the projection source to emit coherent light during an exposure interval comprising at least two sub-intervals, the applied power causing the projection source to have different temperatures during first and second sub-intervals of the at least two sub-intervals; and emitting light from the projection source, wherein the projection source emits light having different wavelengths during the first and second sub-intervals in accordance with the different temperatures of the projection source.
