Wavefront Sensor

(instrument for determining a wave's deformation)

A Wavefront Sensor is an instrument for determining a wave's deformation to control a correcting instrument in an Adaptive Optics (AO) system. Types include:

  • Shack-Hartmann Sensor - focuses spots and senses their position
  • Wavefront Curvature Sensor - focuses spots and measures relative intensity
  • Pyramid Sensor
