Abstract

PURPOSE:To display a prescribed distance range with good distance resolution by measuring the phase delay of laser light projected on an object and detecting the phase output level, and displaying only an area which has a phase in a prescribed distance range by giving brightness. CONSTITUTION:A laser visual sensor is equipped with a level decision device 11 and a distance image display device 12 additionally as compared with a conventional laser visual sensor. Then the decision device 11 detects the level of the phase output of a phase detector 10 and selects only a phase output within the prescribed distance range. The display device 12, on the other hand, displays only the area with the phase within the prescribed distance range by giving brightness. Consequently, the shape of the object 6 within the prescribed distance range is easy to understand and a small distance difference in this distance range can be discriminated.
