Beschreibung
Zusammenfassung:	The invention relates to a device (10) and a method for isolating a trigger signal for a test system (1) of a LiDAR sensor (12), comprising: an optical element (20a, 20b) arranged upstream of a converging lens (18) or a trigger detector (14) in a signal path (SP) of the trigger signal (TS), said optical element being designed to receive the trigger signal (TS) in the signal path (SP) of the trigger signal (TS); the trigger signal (TS) can be passed through and at least partially absorbed by a retro-reflection of the trigger signal (TS) passing through the optical element (20a, 20b), in particular a retro-reflection (RTS) reflected on the surface (22). The invention also relates to a test system for a LiDAR sensor (12). 本发明涉及一种用于LiDAR传感器(12)的测试系统(1)的用于隔离触发信号的装置(10)和方法，该装置带有：在触发信号(TS)的信号路径(SP)中布置在会聚透镜(18)或触发探测器(14)上游的光学元件(20a、20b)，光学元件构造用于，可以使触发信号(TS)通过并且至少部分吸收通过光学元件(20a、20b)的触发信号(TS)的回反射、特别是在表面(22)上反射的回反射(RTS)。本发明还涉及一种用于LiDAR传感器(12)的测试系统。
