Abstract
A lateral shear interferometer using twin three-beam holograms is described. In the interferometer two first-order diffracted light beams from the first hologram play the role of a beam splitter; the second hologram eliminates the effect of tilt. This interferometer has two advantages over the single three-beam hologram lateral shear interferometer: (1) it can be used for small ƒ/No. lens tests; (2) any small aberration of he optical system of the interferometer can be canceled by using the second hologram. In this paper, shearing interferograms of lens aberration, of refractive indices around a flame, and of spouting gas are demonstrated.
