Fig. 3: Fabricated THCMs and characterization of the dual-mode responses.
From: A dual-mode LiDAR system enabled by mechanically tunable hybrid cascaded metasurfaces
a SEM images of the fabricated MS I and MS II. b Projection image of beams in beam array scanning mode. c Beam spot profiles for the deflected beams in beam array scanning mode. These beam spots are marked with orange Xs in (b). d Large-area illumination image in flash illuminating mode. e, f Simulated and measured FWHM values of the beam spots shown in (b) at distances of 10 cm and 20 cm from the emission point, respectively. g Simulated and measured divergence angles of the beams shown in (b)
