DEFECT DETECTION IN AVIATION PLEXIGLASS PARTS BY ANALYZING THE PARAMETERS OF RECORDED SPECKLE FIELDS

The paper presents the results of experimental studies on the use of techniques for applying the method of speckle structures of optical radiation for the tasks of determining the residual life, flaw detection testing, and assessing the health of aircraft cabin glazing elements made of AO-120 aviation plexiglass.
