Time-of-flight sensor

An optical device (1) comprises an emitter (2) for emitting light pulses, a detector (3) for detecting light emitted by the detector (3) and reflected from one or more targets (A, B, C), where the detector (3) comprises a plurality of detection areas (5) covered by lenses (4) arranged to direct incident light onto the plurality of areas (5), and wherein the detector (3) is configured to provide an output signal from each detection zone (5), and one or more processors (6) for processing the output signals wherein the one or more processors (6) are configured to dynamically set signal thresholds for the one or more targets (A, B, C) and to filter out output signals having an amplitude below the signal thresholds. 一种光学装置(1)包括用于发射光脉冲的发射器(2)、用于检测由检测器(3)发射并从一个或多个目标(A，B，C)反射的光的检测器(3)，其中检测器(3)包括由透镜(4)覆盖的多个检测区域(5)，该透镜被布置为将入射光引导到多个区域(5)上，并且其中检测器(3)被配置为提供来自每个检测区域(5)的输出信号，以及用于处理输出信号的一个或多个处理器(6)，其中该一个或多个处理器(6)被配置为动态地设置一个或多个目标(A，B，C)的信号阈值，并且滤除幅度低于信号阈值的输出信号。
