SCATTERING ANGLE MEASURING DEVICE AND SCATTERING ANGLE MEASURING METHOD

摘要

A scattering angle measuring device (200) comprises: a laser (210), configured to emit light to a member to be measured, so as to obtain scattered light formed after the light passes through the member to be measured; a signal acquisition unit (220), configured to move in an incident plane of the light to acquire the scattered light in a plurality of scattering directions in the incident plane; and a processing unit (230), configured to determine, according to the intensities of scattered light in a plurality of scattering directions, the scattering angle of the member to be measured. Therefore, the signal acquisition unit (220) moves in a plurality of scattering directions in the incident plane to acquire the scattered light in each scattering direction, and the processing unit (230) calculates, according to the intensities of scattered light in the plurality of scattering directions acquired by the signal acquisition unit (220), the scattering angle of the member to be measured. Since the signal acquisition unit (220) can move in the incident plane, scattered light in each scattering direction can be acquired by means of only one signal acquisition unit (220), greatly reducing the cost of the measuring device.
