Simulation for sensorless adaptive optics (Confocal microscopy, Modal method)

Introduction

The simulation generates the aberrated PSF on the pupil with Zernike polynomial 5-22 orders, and corrects them with different methods:

  1. GA (Genetic Algorithm). 1000+measurements
  2. Modal method. 350+measurements
  3. SPGD (Stochastic Parallel Gradient Descent). 250+measurements
  4. Optimal Modal method. 150+measurements

All the methods follow the basic direction---> Estimate the Zernike polynomial coefficients based on images with some of measurements.

A comparison of different metrics (the steeper the curve, the better the metric).

  • M1: Variance (aberration.m);
  • M2: Sharpness (aberration2.m);
  • M3: Gradient (aberration3.m);
  • M4: Summation (aberration4.m).
