Abstract

Wavefront sensing is a technique for measuring wavefront aberrations in optical beams, playing a crucial role in various optical systems used for astronomical observations, laser communications, and inertial confinement fusion. As optical systems are being employed in increasingly extreme scenarios, wavefront aberrations have become more pronounced, often exhibiting high temporal variations, which demands more elevated rates of wavefront sensing. This paper introduces a novel wavefront sensing method based on cascaded phase modulation layers capable of achieving ultra-high wavefront sensing speed while maintaining satisfactory accuracy.
