Borehole optical lateral displacement sensor |
摘要 |
There is provided by this invention an optical displacement sensor that utilizes a reflective target connected to a surface to be monitored to reflect light from a light source such that the reflected light is received by a photoelectric transducer. The electric signal from the photoelectric transducer is then imputed into electronic circuitry to generate an electronic image of the target. The target's image is monitored to determine the quantity and direction of any lateral displacement in the target's image which represents lateral displacement in the surface being monitored.
