METHOD FOR LASER SWITCH ON AT STRICTLY DEFINED TIME INSTANTS AT HOLOGRAPHIC DEFECTORCOPY

摘要

Method for switch on of laser at accurately set time instants at holographic defectoscopy includes laser switch on at instant of application of force to article by means of standard switch. Laser is switched on in differential way with delay by 10…120 ms after application of force that acts on article for optimal use of holographic material with fixation of hologram in strictly defined by conditions of tests time instants.
