The invention relates to a
detector array target calibration
system and method. The
system comprises a
light spot acquisition device, a first spectroscope, a second spectroscope, a power meter, a calibration
detector module, and a to-be-calibrated
detector array target, wherein the calibration detector module and the to-be-calibrated
detector array target are in the same distance to the first spectroscope; light spots output by the
light spot acquisition device are transmitted to the calibration detector module and the
detector array target respectively after passing through the first spectroscope, the second spectroscope arranged on an
optical path is used for emitting a beam of light to the power meter; and a first two-dimensional scanning platform and a second two-dimensional scanning platform enable the corresponding calibration detector module and the
detector array target to perform full-coverage scanning of a set path on a plane directly facing the light spots. According to thesystem in the invention, the calibration detector module is matched with the power meter so as to obtain the real
power density of a calibration
light source output by the
light spot acquisition device, and the two-dimensional scanning platforms are arranged, so that the straightness and running precision during full-coverage scanning of the calibration detector module and the detector array target on the set path are ensured.
