Abstract

Phase imaging is used to compare near-field measurements with the corresponding far-field intensity distribution. A liquid-crystal device serves as a phase object that can be programmed as a variable grating. Real-time phase visualization then provides an avenue for direct optimization of complex phase gratings.

摘要

相位成像用于将近场测量结果与相应的远场强度分布进行比较。液晶器件用作相位物体，可将其编程为可变光栅。实时相位可视化随后为复杂相位光栅的直接优化提供了一条途径。
