Abstract
An optical reflection sensor emits light and its reflection from a target object is received. A signal processor carries out a measurement on the received reflected light such as the distance to the target object each time the reflected light is received. Repeatability of measured values is calculated and displayed on a display device incorporated into the housing of the sensor. The display device may have two display areas such that the calculated repeatability and the measured value can be displayed simultaneously. The calculated repeatability may be compared with a specified threshold value, with the result of the comparison displayed. The housing may also incorporate an input device through which a required level of accuracy may be set.
