摘要

In this Letter, we experimentally demonstrate liquid crystalbased moire lenses with a wide and tunable focal lengt h by direct-writing photoalignment. Our moire lenses, which consist of two cascaded diffractive optical elements, have a large range of refractive power between +/- 0.85 m(-1) at 532 nm and a mutual rotation between +/- 90 degrees with high diffraction efficiency (>75%). Based on the as-designed moire lenses, we propose high-dynamic-resolution optical edge detection without any axial shift or substitution of components. The minimum edge width is 13.2 IAM and can be adjusted within 100 IAM by mutual rotation of this device, which has great potential to be used in adaptive and compact optical systems.
