Study on Non-Destructive Testing of Aerial Complex Material by DSPI

Abstract:

A novel method to examine the defect of aerial complex material is presented in this paper. The novel speckle averaging technique for DSPI static measurement is proposed to improve the quality of measurement. A speckle averaging mechanism is designed and fabricated. The measurement result of sandwich structure material of practical aviation engineering is presented. The defect in the final results is clear.
