ABSTRACT:
A method in which, rearwardly of an array-like light source having a plurality of semiconductor lasers arranged in an array, a light detector for detecting the rearwardly emitted beams from the semiconductor lasers is provided and the peak value of each of the semiconductor lasers is detected by the light detector so that the peak values of the semiconductor lasers can be made equal to one another, whereby the quantity of light from each of the semiconductor lasers is regulated.
