(a) Fiber optic Shearography system
The laser beam is launched into the HiBi fiber at 45 degrees to the fiber axis by means of a half-wave plate. The light emerging from the fiber is used to illuminate the object under test. A zoom lens images the test object and the Wollaston prism gives two sheared speckle images which are orthogonal to each other. An analyzer placed is then aligned such that its transmission axis makes an angle of 45 degrees with the principal section of WP, so that the two shear images can interfere with each other. Interference fringes are produced at the CCD image plane and displayed in real-time on a monitor.
