论文摘要
具有二进制和多级调制的相位和振幅空间调制器（SLM）广泛可用，并为全息应用提供了广泛的技术。虽然用多级相位单相的SLM生成的重播场的质量明显高于同等二进制相位单相的SLM产生的质量，但在这封信中提供了证据，表明此改进并不标志着振幅SLM的标记，其中多层设备仅提供了比其二进制对方的小益处。讨论了有关此的启发式和数值理由并得出结论。
Phase and amplitude spatial light modulators (SLMs) capable of both binary and multi-level modulation are widely available and offer a wide range of technologies to choose from for holographic applications. While the replay fields generated with multi-level phase-only SLMs are of a significantly higher quality than those generated by equivalent binary phase-only SLMs, evidence is presented in this letter that this improvement is not as marked for amplitude SLMs, where multi-level devices offer only a small benefit over their binary counterparts. Heuristic and numerical justifications for this are discussed and conclusions drawn.
