Paper Abstract

The present paper investigates the application of the phenomenon of instability development on the charged surface of a photothermoplastic carrier for visualization of interferograms of a hydroelectropump body oscillation during vibration loading. It is demonstrated that the concentration of the surface-active substances determines the value of the resolution capacity due to the reduction of the coefficient of surface tension of the phase rheological media. The characteristics of some PTPC show that the application of photothermoplastic carrier - surface-active substances (PTPC plus SAS) in holography (interferograms) is not only possible, but also necessary. It is determined by the fact that at a quite high holographic sensitivity (up to 10-7 J/cm2) the frequencies above 1500 mm-1 can be recorded with the values of diffraction efficiency much more than those for hologen-silver materials. An optical configuration based on the photothermoplastic recording (PTPR) is suggested for the inline optical diagnostics and standardization of the products in the real-time scale. Dry development of the images in the real-time scale and instant fixation of images on the photothermoplastic carriers (PTPC) followed by the computer analysis used to compare the product and the standard allow us to gain in time and areas.
