It can provide interactive digital teaching in schools. This, in turn, produces a light field identical to the captured scene and scatters onto the hologram to reconstruct the object view. A beam of laser light is split into two identical beams with one of the split beams (illumination beam or object beam) is directed at the object and then scattered on to the recording medium. The panels are subjected to a high humidity environment which causes adhesive degradation. Periodically the panels are holographically examined. The other beam (reference beam) is redirected by the use of mirrors onto the recording medium without going through the object. It's offered in a variety of finishes—from natural to matte to holographic. Pros Both techniques very sensitive, able to measure movements and vibrations of order of λ . Displayers tend to become three-dimensional. Laser shearography uses laser light for making the image even before the surface is subjected to stress and creates a new image.
