Abstract
An optical displacement sensor is described in which only a pair of large‐diameter fibers is used rather than a branched bundle of many small‐diameter fibers. The basic idea of the two‐fiber sensor is that the axes of the fibers are at an angle to one another at the sensor face, rather than parallel as is the case for the many‐fiber configuration. The sensitivity of this two‐fiber sensor is approximately the same as the most sensitive configuration of the many‐fiber sensor.Keywords
