Abstract

A method for measurement of misalignment in an optical system using wavefront sensing in a two-lens telescopic system is reported. Using Shack-Hartmann wavefront sensor data and ABCD matrix, mapping between Zernike coefficients with known misalignment of optical system is carried out. Results are validated experimentally using a two-lens telescopic system, and then compared with simulated values of a Ritchey-Chretien telescopic system for measuring misalignment. Also, it was demonstrated that ABCD matrix can only work for on-axis misalignment estimation and cannot work for off-axis.
