Distance measuring device |
摘要 |
A distance measuring device (1) having an emitting unit (6) for emitting a light beam onto an object (2); a photoreceiver (10) for receiving and converting the light beam reflected by the object (2) into a first electric signal (SR) related to the distance (D) between the object (2) and the distance measuring device (1); a processing circuit (11) for processing the first electric signal (SR) to supply a second electric signal (ST) related to the distance (D) and to the internal circuit delays ( DELTA RIT) introduced by the processing circuit (11) when processing the first electric signal (SR); a signal generating circuit (7) cooperating with the processing circuit (11) to generate a delay signal (SRIT) related to the internal circuit delays ( DELTA RIT) in the second electric signal (ST); and a filtering and matching circuit (12) for eliminating from the second electric signal (ST) the contribution of the circuit delay ( DELTA RIT) indicated by the delay signal (SRIT), so as to supply a distance signal (SD) indicating the distance (D) of the object (2) from the distance measuring device (1). <IMAGE> |
