A new holographic lateral shear interferometer with two three-beam holograms is described which is useful for the real-time measurement of large liquid surface deformations. In the interferometer, it is shown theoretically and experimentally that the aberrations of the optical system can be cancelled and the amount of shear changed easily. The shearing interferograms of the liquid surface deformations caused by a water strider, etc. are demonstrated.
