FIELD: instrumentation.
SUBSTANCE: for non-destructive methods of control of internal structures of objects. The substance of the invention consists in the fact that a laser ultrasonic flaw detector comprises a pulse laser, connected via optic fibre with an optic-fibre converter made in the form of a single unit arranged on the investigated object, and comprising a plate of the optic-fibre generator, and also a piezoreceiver connected via an amplifier with an analogue-digital converter connected to a computer, at the same time the optic-acoustic generator and the piezoreceiver are spatially distanced and placed on inclined acoustic lines that contact with investigated material, and the laser, analogue-digital converter and power supply unit are in a separate body.
EFFECT: expansion of functional capabilities of a device due to usage of different types of acoustic waves.
