Background:

  • Shack-Hartmann wavefront sensors are crucial for adaptive optics.
  • Conventional and cylindrical lenslet arrays have limitations in pixel count and readout noise.
  • Existing designs can limit performance in demanding applications like astronomy.

Purpose of the Study:

  • To present an improved Shack-Hartmann wavefront sensor design.
  • To reduce detector pixel requirements and signal degradation from readout noise.
  • To enhance suitability for astronomical adaptive optics systems.

Main Methods:

  • Introduced optical binning to a cylindrical (lenticular) lenslet array Shack-Hartmann sensor.
  • Performed analytical noise considerations.
