Wavefront Phase Sensors Using Optically or Electrically Controlled Phase Spatial Light Modulators


Systems for optical wavefront sensing and control based on a phase contrast Fourier domain filtering technique. Optically or electronically controlled phase spatial light modulators (SLM) are used as the Fourier domain filter. A direct adaptive-optic feedback system using the optical wavefront sensing systems. A differential Zernike filter is also disclosed.
