Sensor

摘要

The probe has a feeler module (60) comprising a feeler (100) held by elastic elements in a resting position relative to a fixed element. The feeler is movable from the resting position in response to a deflection force. A detection system detects displacements of the feeler and comprises a light source (68) e.g. LED. An optical image sensor e.g. charge-coupled device sensor (61), receives light emitted by the light source, where a spatial distribution of intensity on the optical image sensor changes according to the displacements of the feeler.
