Optical sensor for inspecting surfaces of boreholes, has light conductors, radiation source, coupling elements, and deflecting bodies arranged such that exit radiation beams are produced without beam splitter by reflection at bodies

摘要

The sensor has a sensor body (1), light conductors (2a, 2b, 2c), a radiation source (3), and coupling elements (4, 5), where radiation exits (6, 7, 8) are provided for exiting the electromagnetic radiation from the sensor body. Radiation deflecting bodies (10, 14) deflect the electromagnetic radiation and are arranged in the sensor body. The light conductors, the radiation source, the coupling elements, and the deflecting bodies are arranged such that two exit radiation beams are produced without a beam splitter by reflection at the deflecting bodies.
