Abstract

In the introduced paper on an example of the mobile pulse holographic set-ups, designed by authors and inserted to the large industrial enterprises of Russia the requirements to the basic units of holographic measurement complex, intended for vibration analysis of large-scale objects under out-of- laboratory conditions are analyzing. It is shown the quality of obtained measurement information depends not only from coherent properties of laser and quality of interferometer, but also from the quality a control system of laser radiation. In particular, for obtaining the reliable and reproduced results of analysis of actual vibration processes (non-stationary, random, multicomponent vibrations) the system of control and synchronization play a major role. The methods of synchronization of laser radiation with the phases of investigated dynamic processes, designed by authors, are considered. The capability of the development the newest mobile holographic complex, including the powerful superstable double-pulse laser, kit of removable digital interferometers with selective sensitivity and unified computer system of control of laser radiation, recording and processing of digital interferograms are considered. The new design solutions of the main unit of a complex are discussed.
