  • Available measurement methods of laser beam quality can't reach the demands of speed and accuracy simultaneously. In order to take speed and precision into account, a double-slit scanning method was proposed. The complexity of data analysis reduced because attenuator was not used in the optical path. Embedded technology was selected to control and process the data, and real time data processing can be realized while the whole system was easy to carry. After theoretical analysis and experimental verification, the results show that this method can get fast synchronous measurement of dual axis shaft power distribution. Dynamic range can reach 70dB and scan rate is from 2Hz to 18Hz. This method can be used for the analysis of continuous or pulsed laser beam and is helpful for reaching the demands of both measurement speed and accuracy.
