Title: Multiple optical axis photoelectric sensor
Inventor: HAYAKAWA DAISUKE
IPC: G01V8/20
Filed: 2002-03-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a multiple optical axis photoelectric sensor which can avoid the influence of coherent light without fail, even if it is in an environment where it receives coherent light from other devices.  <P>SOLUTION: When scan action incapable of detecting coherent light in nonprojection periods have continued a specified number of times, this photoelectric sensor varies the scan cycle at random. Hereby, it becomes possible to detect the coherent light, and interference can be avoided by ordinary interference-avoiding action. In this case, the possibility of executing the same interference-avoiding action as in other multiple optical axis photoelectric sensors is very low, because this varies the scan cycle at random.  <P>COPYRIGHT: (C)2004,JPO
