[0054]), wherein the optical module (802) is configured to redirect (Path 2, see Fig. SA) a LiDAR signal emitted by the LiDAR device under test from a predetermined portion of the field of view (para. [0097], [0115]) to the target simulator module, wherein the predetermined portion is adaptable (para. [0054]: since the LiDAR device is a scanning LiDAR device, it is implicit that the predetermined portion of the field of view changes during the scanning), wherein the target simulator module (804, 810, 812, 814, 816, 818, 820) comprises a receiver unit (804), wherein the receiver unit is configured to receive the LiDAR signal redirected by the optical module (see Fig. SA), wherein the target simulator module (804, 810, 812, 814, 816, 818, 820) comprises a manipulation unit (810, 812, 814, 816, 818, 820), wherein the manipulation unit is configured to manipulate the received LiDAR signal, thereby generating a manipulated LiDAR signal (para. [0100], [0116]; Step 1404 in Fig. 14), and wherein the target simulator module (804, 810, 812, 814, 816, 818, 820) further comprises an emitter unit (36), wherein the emitter unit is configured to emit the manipulated LiDAR signal (para. [0120]; Step 1406 in Fig. 14). 2. The LiDAR test system according to claim 1, wherein the optical module is configured to scan the field of view, such that LiDAR signals from different portions of the field of view are redirected to the target simulator module consecutively .[0054](with fig. 4B) 3. The LiDAR test system according to claim 2, wherein a scanning pattern of the optical module is synchronized with a scanning pattern of the LiDAR device under test.[0195](with fig. 4B) 4. The LiDAR test system according to claim 1, wherein the optical module is configured to redirect the manipulated LiDAR signal to the LiDAR device under test.(Fig. 8A,B) 5. The LiDAR test system according to claim 1, wherein the optical module comprises a scanning mirror.(fig. 8A MEMS mirror) 8. The LiDAR test system according to claim 1, wherein the optical module comprises at least one optical component (852)being configured to reflect and/or refract the LiDAR signal.(fig. 8b) 9. The LiDAR test system according to claim 1, wherein the predetermined portion of the field of view is smaller than the field of view.[0054,0115] 10. The LiDAR test system according to claim 9, wherein the predetermined portion of the field of view is equal to or smaller than 50% of the field of view, smaller than or equal to 25% of the field of view, or smaller than or equal to 10% of the field of view.[0054](raster scan for example with one by one point) 11. The LiDAR test system according to claim 1, wherein the LiDAR test system comprises a control module, wherein the control module is configured to control the optical module, the target simulator module, and/or the LiDAR device under test.[0095] 12. The LiDAR test system according to claim 1, wherein the receiver unit comprises an optical-to-electrical converter.(photo detector is optical to electrical converter) 13. The LiDAR test system according to claim 1, wherein the emitter unit comprises an electrical-to-optical converter.(laser is electrical to optical converter) 14. The LiDAR test system according to claim 1, wherein the emitter unit comprises a laser diode, [0086]wherein the laser diode is configured to emit the manipulated LiDAR signal.[0054] 15. The LiDAR test system according to claim 1, wherein the optical module is configured to redirect at least two LiDAR signals emitted by the LiDAR device under test from the predetermined portion of the field of view to the target simulator module simultaneously, wherein the target simulator module is configured to manipulate the at least two received LiDAR signals, thereby generating at least two manipulated LiDAR signals, and wherein the target simulator module is configured to emit the at least two manipulated LiDAR signals. (para. [0071], [0015] and Fig. 4B: the LiDAR under test can be a multi-beam flash LiDAR transmitting more than one beam simultaneously); 16. The LiDAR test system according to claim 1, wherein the LiDAR test system comprises a sensor array, wherein the optical module is configured to partially redirect the LiDAR signal emitted by the LiDAR device under test to the sensory array. (Splitter 802 and Path 1 in para. [0098] and Fig. 8A); 17. The LiDAR test system of claim 16, wherein the sensor array is configured to determine a scanning pattern of the LiDAR device under test, a beam shape of the LiDAR signal emitted by LiDAR device under test, and/or a pulse shape of the LiDAR signal emitted by the LiDAR device under test. (Path 1 in para. [0098] and Fig. 8A); 18. The LiDAR test system of claim 16, wherein the optical module is configured to redirect the LiDAR signal to the sensor array from the whole field of view of the LiDAR device under test, from the field of view of the LiDAR device under test outside of the predetermined portion of the field of view, or from the predetermined portion of the field of view.

Patentability shall not be negated by the manner in which the invention was made. Claim(s) 6 is/are rejected under 35 U.S.C. 103 as being unpatentable over D1 in view of D4 US 20190086550 A1. Regarding claim 6 D1 does not teach but D4 teaches as an alternative to mems using 6. The LIDAR test system of claim 5, wherein the scanning mirror is a 2D galvanometer scanner or a digital micromirror device.[0053] It would be obvious to one of ordinary skills in the art at the time of filing to modify teachings by D1 with teaching by D4 in order to use other well known devices for light redirection in LIDAR system in case MEMS device is not available.
