Abstract
1. Лазерно-ультразвуковой дефектоскоп, содержащий импульсный лазер, соединенный через оптоволокно с оптико-акустическим преобразователем, а также пьезоприемник, соединенный через усилитель с аналогоцифровым преобразователем, подключенным к компьютеру, отличающийся тем, что оптико-акустический преобразователь выполнен в виде единого блока, расположенного на исследуемом объекте, и содержит пластину оптико-акустического генератора, помещенную между исследуемым объектом и прозрачным цилиндром, на торце которого расположен пьезопреобразователь, а фаска цилиндра сопряжена через оптическую систему с оптоволокном. ! 2. Лазерно-ультразвуковой дефектоскоп по п.1, отличающийся тем, что акустические импедансы материалов прозрачного цилиндра и пластины оптико-акустического генератора равны.1. Laser-ultrasonic flaw detector containing a pulsed laser connected through an optical fiber to an optical-acoustic transducer, as well as a piezo receiver connected via an amplifier to an analog-digital transducer connected to a computer, characterized in that the optical-acoustic transducer is made in the form of a single unit located at the object under study, and contains a plate of an optical-acoustic generator placed between the object under study and a transparent cylinder, at the end of which there is a piezoelectric transducer zovatel and chamfer cylinders interfaced through an optical system with an optical fiber. ! 2. Laser-ultrasonic flaw detector according to claim 1, characterized in that the acoustic impedances of the materials of the transparent cylinder and the plate of the optical-acoustic generator are equal.
