DEVICE FOR Holographic Interferometry rotating objects

摘要

The invention relates to a device for holographic interferometry, and can be used to study the deformation and vibration of various objects during their rotation.; Technical Solution - extension of the class of the objects and increase the range of admissible velocities of their rotation. In the apparatus for holographic interferometry rotating object, comprising a pulsed ruby ​​laser, wherein the Q-switching is made in the form of a prism of full internal reflection, optical scheme for forming the object and reference beams and the recording medium inside the resonator ruby ​​laser passive shutter is additionally introduced.; The concentration of the antireflective solution is selected so that at any speed could form a single radiation pulse. The combined use of a passive shutter and a rotating prism leads to improvement of the radiation parameters, and increase of Q-switching rate, enabling to record holograms more large objects in a certain phase of the rotational movement. 1 yl.
