Tunable Axicons Generated by Spatial Light Modulator with High-Level Phase Computer-Generated Holograms
Axicon is an interesting optical element for its optical properties. This paper presents an approach to dynamically generated tunable axicons with a spatial light modulator (SLM). 256-level phase computer-generated holograms (CGHs) were loaded into the SLM to simulate the positive and negative axico...
