Optical sensor including an optical fiber, a fiber elongation, deflecting mirror for coupling and decoupling the light useful for detecting clearances inside cavities of diameter less than 500 micron

摘要

Optical sensor head including an optical fiber (10) via which light in the sensor head is coupled or decoupled, a fiber elongation (11) coupled optically at one end to the optical fiber and at the other end to a deflecting mirror (12) for coupling and decoupling the light, a composite structure (15) for reception of part of the optical fiber (10) and fiber elongation (11) in a fiber channel (16).
