Latest Patents

One of his latest patents is a method and device for non-destructive real-time measurements of residual stresses in planar and non-planar objects. This invention utilizes optical holographic interferometry techniques to perform non-destructive measurements. The holographic interferometer consists of a holographic probe that illuminates the investigation area with coherent light and collects the scattered light. It also includes a means for performing a non-destructive dislocation release pulse of the residual stresses by exposing the object to a high-current electric pulse. This allows for accurate measurements of residual stresses on surfaces with high curvatures and in hard-to-reach locations.

Another significant patent by Andrushchenko is the method and device for real-time non-destructive determination of residual stresses in objects using optical holographic interferometry. This process involves registering a hologram of the object's initial state, releasing residual stresses through a high-current electric pulse, and then creating an interferogram to determine the residual stresses based on the fringe patterns observed.
