摘要	A method for measuring the laser power of a forward multiple beam generated by a laser diode array comprising at least two laser diodes, the method comprising a generation step, comprising generating the forward multiple beam; a separation step, comprising separating at least part of the forward multiple beam into individual beams (31, 32, 300, 301, 302, 303), the number of individual beams being equal to the number of laser diodes in the laser diode array, the arrangement being such that each individual beam comprises light originating from a single laser diode and a measurement step, comprising measuring the laser power of each individual beam by means of photo detectors (121, 122, 125, 126, 127, 128). The separation may be performed in space, by means of an imaging lens or making use of vignetting of the collimator lens, or in time.
