WIPO Patent Application WO/2023/120012
Kind Code:
A1
Abstract:
This measurement device (1) comprises: a light emitting unit (10) that emits pulsed light; an imaging sensor (22) that outputs a signal value corresponding to an amount of exposure for each pixel (221); a timing control unit (32) that exposes reflected light to the pixel (221) of the imaging sensor (22) during an exposure period of an exposure width (Gw) which is set in accordance with an area to be measured and is shorter than a pulse width (Lw) of the pulsed light; and a calculation unit (36) that calculates an arrival time (Tx) of the reflected light, on the basis of the signal values (Sa to Sd) corresponding to the three or more consecutive exposure periods (A to D) that can include the pulse width (Lw).
