Abstract
A bore hole probe instrument having a point source of light, passing through a flexible tubular portion. The point of light, which originates at one end of the flexible tubular portion, is established for example by means of fibre optics, a laser or the like. At the other end of the flexible tubular portion there is located an automatic camera having an image screen, on which the point of light is received. As the flexible tubular portion bends, to follow the path of the bore hole, the light spot will be deflected on the image screen. The camera will photograph the position of the light spot on the image screen thereby providing an indication of the deviation of the bore hole.
Claims12
A bore hole probe for determining the path of a bore hole and comprising
- a source of radiant energy
- support means for said source of radiant energy;
- radiant energy sensitive means, sensitive to exposure to said radiant energy;
- fibre optic thread means for forming said radiant energy into a narrow spot adapted for transmitting said radiant energy, with said source of radiant energy at one end, the other end of said fibre optic thread means being adjacent to said radiant energy sensitive means, and said radiant energy sensitive means defining a predetermined area having length and breadth, upon a portion of which said spot of radiant energy may be received, and recorded, while the remainder of said area of said sensitive means remains unaffected thereby, whereby to record the position of said spot of radiant energy on said predetermined area of sensitive material;
- support means for said radiant energy sensitive means;
- flexible connection means extending between said radiant energy source support means and said support means for said sensitive means, permitting relative angular movement between said spot of radiant energy and said radiant energy sensitive means and, rigid support means surrounding said fibre optic thread means within said flexible connection means.
