Abstract

Лазерный ультразвуковой дефектоскоп, содержащий импульсный лазер, соединенный через оптоволокно с оптико-акустическим преобразователем, выполненным в виде единого блока, расположенного на исследуемом объекте, и содержащим пластину оптико-акустического генератора, а также пьезоприемник, соединенный через усилитель с аналого-цифровым преобразователем, подключенным к компьютеру, отличающийся тем, что оптико-акустический преобразователь и пьезоприемник пространственно разнесены и размещаются на наклонных звукопроводах, контактирующих с исследуемым материалом, а лазер, аналого-цифровой преобразователь и блок питания размещены в отдельном корпусе. A laser ultrasonic flaw detector containing a pulsed laser connected through an optical fiber to an optical-acoustic transducer made in the form of a single unit located on a test object and containing a plate of an optical-acoustic generator, as well as a piezoelectric receiver connected via an amplifier to an analog-to-digital converter connected to a computer, characterized in that the optical-acoustic transducer and the piezoelectric receiver are spatially spaced and placed on inclined sound ducts, contacting x to the analyte, and a laser, an analog-digital converter and the power supply are arranged in a separate housing.
