Abstract: A probe for inspecting an anchor borehole has a video head provided with a color CCD sensor, a lens, a conical viewing window, and light-emitting diode for illuminating and optically scanning a borehole surface. The probe also has a travel sensor, an electronics module including two position sensors, a memory module, and a battery section carrying an infrared interface. The probe is cableless and autarchic. The battery section is secured to a leading end of a push rod.

Abstract: The invention relates lo a device for examining rotor drilled holes, which comprises a probe which comprises an optical detection device and which can be displaced in the drilled hole by means of a push rod. The rotor drilled hole probe (1) comprises a video head (10), which comprises a colour CCD-sensor (11) with a lens (12) which is provided with a cone-shaped mirror (13) and an observation window, in addition to light-emitting diodes (15), a path sensor (20), an electronic part (21), a storage module (22) and battery part (23) whereon an infrared interface is arranged.
