Optical system performs at least one reference measurement as transition time measurement for optical signal in two reference light conductors to determine distance measurement correction

摘要

The system has a measurement unit that emits an optical signal and detects a reflected signal and a control unit that determines the distance between reference and target objects based on a transition time measurement. The measurement unit is connected to two reference light conductors with defined different lengths and performs at least one transition time reference measurement in both reference light conductors to determine a correction value. The system has a measurement unit (3) that emits an optical signal (13) for distance measurement and detects a reflected signal (14) and a control unit (7) that determines the distance between a reference object (1) and target objects (2) in the observation region based on a transition time measurement. The measurement unit is connected to two reference light conductors (10,11) with predefined and different lengths and the measurement unit performs at least one reference measurement as a transition time measurement for the optical signal in both reference light conductors to determine a distance measurement correction value.
