Abstract

In quantitative investigations of heterogeneities in transparent media in such fields as experimental gas dynamics, ballistics, thermal physics, physics of plasma, control of large optical elements, etc., classical interference and holographic techniques are most effective. They make possible the a posteriori analysis of the object waves reconstructed from holograms by shadow, color, and interference methods with the change of initial tuning of the device and with the increase of measurement sensitivity. The recording of the object initial hologram or interferogram, for example, on a gas-dynamic stand or during the control of large mirrors, can be hampered by the external vibrations or by difficulties of joining together the object and the interferometers. This is conditioned, as a rule, by the off-axis location of the reference beam in the interferometer circuit, for example, Zehnder-Mach type, and by the existence of the relatively distant large optical elements. This paper presents a new interferometer that doesn't have those drawbacks.
