| Abstract: | Principle of DSPI is used to set up a optical system to measure plane displatment.In this sysytem the CCD is used to receive the speckle image,the interference fringes are analysed which are got from computer digital image processing and the plane displacement of ground glass is calculated.Finally,the sensitivity,scope and precision of this system's measurement are discussed and analyzed. |
