Detailed Documentation

This program calculates the wavefront reconstruction matrix for Shack-Hartmann wavefront sensors. The Shack-Hartmann wavefront sensor is an optical measurement device that analyzes wavefront distortions after light passes through optical components. Specifically designed for 10x10 subaperture configurations, the program employs a reconstruction algorithm that processes local wavefront slopes measured at each subaperture to reconstruct the complete wavefront profile. The implementation involves several key computational steps: first gathering slope data from all subapertures, then constructing a system matrix that relates slope measurements to Zernike polynomial coefficients, and finally performing a least-squares matrix inversion to obtain the reconstruction matrix. This matrix enables conversion between measured slope data and reconstructed wavefront phases, significantly enhancing the sensor's accuracy and reliability for optical analysis. Through this computational approach, users can obtain precise quantitative assessments of wavefront distortions in optical components, facilitating more accurate research and experimental work in optical system characterization and correction.
