FIELD: optical probes. SUBSTANCE: optical probe has base-mounted crystal cavity and vibration source, and also optical fiber installed on first arm of crystal cavity with aid of hold-down device. The latter has grip and is mounted on base for shifting grip relative to first arm of crystal cavity; optical fiber is secured on base and disposed at certain angle to first arm of crystal cavity for varying this angle. Hold-down device may be made in the form of two strips of which first one is mounted on base for turning and displacing in plane perpendicular to optical fiber; first strip mounts second one for turning relative to the former in plane parallel to optical fiber and for locking relative to the latter. EFFECT: enhanced probe sensitivity and operating reliability. 3 cl, 6 dwg |
