    摘要: A bore hole scanner includes light projecting means (11 - 13, 5) for projecting a light beam toward a bore hole wall surface, a conical mirror (4) arranged coaxially with respect to a sonde (14) for condensing light reflected from the bore hole wall surface, image forming means (3) arranged in front of the conical mirror (4), photoelectric transducing means (2-1) for converting a light signal into an electric signal, optical fibers (2-2) for introducing an image, which is formed on concentric circles by the image forming means (3), to the photoelectric transducing means (2-1), data processing means for scanning and extracting signals from the photoelectric transducing means (2-1), and for generating and processing image data indicative of the bore hole wall surface, and sonde position detecting means (8 - 10) for detecting the orientation and position of the sonde. Rotating portions are dispensed with by using the conical mirror and optical fibers, and a linear CCD array can be used as the photoelectric transducing means.

    摘要: A method and apparatus for observing the wall of a bore hole (22) are disclosed.
    An optical head (12) is rotated while a sonde (11) is moved up or down within a bore hole (22), and a beam of light from a light source (22) is projected toward the wall of the bore hole (22) via a lens (21), slit (22), half-mirror (19), mirror (15) and lens (14). Light reflected from the bore hole wall is extracted from the half-mirror (19) via a slit (17) and a photoelectric transducer (18) so that the bore hole wall may be continuously observed. By separating the reflected light into spectral components and processing them, color tone logging and other observations can be performed. The orientation of the sonde (11) is sensed by an azimuth finder (23) and rotation gauge (24), and the inclination of the sonde (11) is sensed by a dipmeter (25). Displacement of the sonde accompanying each unit length of up- or -down movement of the sonde to obtain the position being observed by the sonde.
