Abstract
Investigations of fast processes in transparent media are being successfully performed by means of coherent optics methods such as interference, correlation, laser Doppler anemometry (LDA), etc. All these methods require splitting and further bringing together laser beams and following the processing of a useful signal. It is very difficult to fulfill these requirements with the help of traditional optical means, especially for many beams with complex wave fronts. In these cases one has to use optical schemes with a great number of elements, which results in great losses at reflection, in depolarization of the beams, in worsening of the device vibration stability, and in climatic changes. It is possible to get rid of all these disadvantages by using holographic optical elements in such devices.
