In this work, a combined system including FLC high‐speed polarization rotator, liquid crystal polymerizable polarization grating, FLC switchable Dammann Grating is proposed to form tunable diffractive spot matrices and acquire depth information. By adjusting electric field, the grating can be switched between diffractive state showing 4 by 4 optical spots arrays in two areas and non‐diffractive state, respectively. At a low driving voltage of 5V, our approach renders the gratings electrically tunable with a fast response time of 50μs, which has the potential for LiDAR applications. [ABSTRACT FROM AUTHOR] |
