Simultaneous measurement of 2-D curvature, twist and slope with a five-aperture shearing camera
In this paper, a new speckle shearing camera is designed for simultaneous recording 2-D curvature, twist and slope on a double exposed specklegram. The specklegram yieldsthirteen distinct diffraction halos when subjected to filtering. The curvature, twist and slope fringes can be obtained by filtering via the appropriate halos.
