| 摘要 |
An apparatus for measuring the relative positions of hole patterns is disclosed wherein two or more fiber optic bundles disposed within first and second holes and connected to one or more sources of light and light sensitive, position sensing devices provide two, three, four or five axis measurements of the relative positions of the two holes. By measuring the position of the light from the source transmitted via an optical bundle in the first hole and received by an optical bundle in the second hole, a precise measurement system that senses mismatch and the direction thereof with a very high degree of accuracy is achieved. The movement of plane surfaces may also be measured with the present apparatus by attaching either the transmitting or receiving side of the apparatus to a part which is subjected to a load, and measuring the resulting change in the position of the light beam illuminating the light sensitive, position sensing device. |
