Claim 11:
12. A non-transitory computer-readable medium having processor-executable instructions stored thereon for testing a distance sensor test bench having a folded optical path, wherein the processor-executable instructions, when executed, facilitate performance of the following:
in a simulation mode, feeding a receive signal (SRX) or a derived receive signal (S′RX) through a delay unit of a testing device with a settable time delay (tdelay, set) during testing of a distance sensor to form a delayed signal (Sdelay), and, in order to test the distance sensor, radiating the delayed signal (Sdelay) or a derived delayed signal (S′delay) via a radiating element of the testing device; and
in a test mode:
generating, by a test signal unit of the testing device, a test signal (Stest);
radiating, by the radiating element of the testing device, the test signal (Stest) or a derived test signal (S′test); and
scanning a quiet zone to measure planeness of incoming waves in the quiet zone, wherein scanning the quiet zone comprises determining, by an analysis unit of the testing device, phase angles (Phi) and/or amplitudes (A) of a plurality of receive signals (SRX) or a plurality of derived receive signals (S′RX).
