Abstract
This invention concerns a device for the non-destructive inspection of a part (6) by means of optical holography. This device includes a source (2) emitting a laser beam and a holographic camera (4) placed at a certain distance from the source (2) and close to the part to be inspected (6); the laser beam is transmitted from the source (2) to the camera (4) by means of a beam of sequenced optical fibers (8) suitable for transmitting a high-powered laser beam, while maintaining the coherence of space and time of this laser beam. The device is suitable for interferometry nondestructive inspection applications.
