Laser holographic interferograms with large field of view
Abstract
A description is given of an approach which makes it possible to obtain laser holographic interferograms with a field of view as large as 160 deg. Use is made of holographic scatter plates to increase significantly the quality of the interferograms. The described technique can be applied in any case in which a change of refractive index is introduced into the object field between exposures.
