High-precision wavefront measurement based on hybrid differentiation

Year: 2025

Type: article

Abstract: In this paper, we propose what we believe to be a novel wavefront measurement method based on hybrid optical differential techniques within the framework of weak measurement. By establishing weak couplings between rotational and lateral components, we achieve hybrid optical differential calculations of the input wave function in both angular and lateral dimensions. This approach significantly simplifies wave function reconstruction algorithms by requiring only a single post-selection measurement, combined with a Zernike coefficient search algorithm. Unlike conventional methods, our technique eliminates the need for phase unwrapping, thereby simplifying both the experimental setup and measurement procedures. The proposed method demonstrates significant potential for advancing high-precision wavefront sensing technology.
