More Information
Summary:This optical distance measurement device (3) comprises a photodetector (32), which has photodiodes (32-1)-(32-N) for receiving interference light output from a light interference unit (31) and outputting interference light detection signals, and a switch (33), which is for selecting one detection signal from among the detection signals output by the photodiodes (32-1)-(32-N). A distance measurement unit (35) calculates the distance to an object of measurement (1) on the basis of the detection signal selected by the switch (33).
