Optical probe for testing surfaces of borehole, has radiation-deflection body that is arranged in probe body for reflecting bundle of radiations, and radiation outlet discharging reflected bundle of radiations

摘要

The probe has a body (1), and radiation sources producing parallel bundle of radiations (2) e.g. laser radiation, with different radiation frequencies. Light conductors, coupling elements and coupling areas introduce the bundle of radiations into the body. A radiation-deflection body (3) arranged in the body reflects the bundle of radiations. A radiation outlet discharges the reflected bundle of radiations. The bundle of radiations falls on the deflection body with a concave reflection surface (4). A focus point (5) of the bundle of radiations falls on a surface (6) of a borehole to be tested.
