Research on Atmospheric Turbulence Distortion Measurement Based on Compressed Sensing Technology

Abstract

The Hartmann wavefront sensor can measure the phase change of atmospheric turbulence in real time and realize the measurement of the distorted wavefront signal of atmospheric turbulence. However, existing Hartmann wavefront sensor microlens arrays are generally small, which limits their spatial resolution capabilities. By introducing compressed sensing technology into wavefront detection, this paper breaks through the limitations of the traditional Nyquist sampling theorem and achieves higher resolution spatial wavefront detection with a smaller microlens array.
