An Improved Centroid Detecting Calculation Method of Hartmann Wavefront Sensor
The limitation of traditional threshold moment centroid algorithm for Hartmann wavefront sensor is analyzed. An improved algorithm is proposed, which the centroid detection window size is optimized and searched automatic with the gray integral principle, finally uses the intensity weighted centroiding algorithm to calculate. Simulation and analysis prove the feasibility, which is beneficial to improve the wavefront sensor centroid detecting accuracy.
