title = "Detecting Deformable Mirrors through Dynamic Phase Measuring Deflectometry",
abstract = "Deformable mirrors are essential components of adaptive optics, often requiring real-time measurement of their surfaces over a wide dynamic range. Traditional phase measuring deflectometry, based on sequential phase modulation, typically involves displaying multiple phase-shifted fringe patterns and capturing multiple frames of fringe patterns for phase reconstruction, which struggles to meet the real-time requirements of dynamic measurements. To address this issue, we propose a method based on dynamic digital Moir{\'e}fringe phase measuring deflectometry. By employing digital Moir{\'e} phase-shifting techniques, our approach only requires capturing two frames of fringe patterns reflected from the mirror surface to achieve high-precision phase reconstruction. Simulation and experimental validation confirm that this method offers excellent real-time measurement capability with low sensitivity to environmental vibrations.",
