Comparative Analysis of Interferometric and Diffraction-Based Phase Calibration for LCoS Spatial Light Modulators

Abstract

Optical systems that rely on precise phase modulation commonly use Liquid Crystal on Silicon (LCoS) Spatial Light Modulators (SLMs), and the optical fidelity of applications such as beam shaping, adaptive optics, and holography depends on precise phase calibration. In this work, we compare two primary phase calibration techniques for LCoS SLM setups: a Michelson interferometer-based method and a diffraction-based self-referenced interferometric method. The Michelson interferometric technique measures phase shifts directly via fringe pattern intensity analysis, offering high accuracy in characterizing the global phase response, although its practical downside is the requirement for a complicated and vibration-sensitive setup. In contrast, the diffraction-based interferometric technique, which uses a binary phase grating to generate an interfering beam, provides a faster assessment via a simpler and more robust calibration process, albeit with slightly lower accuracy. While the Michelson interferometric technique offers higher precision for mapping the average phase response, the diffraction-based calibration method yields results more quickly and may be a better choice for applications requiring rapid data acquisition or operation in less stable environments. The unique value of this study lies in its direct, side-by-side experimental comparison of these two foundational calibration techniques using the same device and consistent methodologies, evaluating them across key performance areas. Therefore, this study helps inform the selection between the two techniques by providing justification beyond absolute accuracy, considering factors like complexity, robustness, and the experimental setting.
