Misalignment-Induced Aberration Compensation for Off-Axis Reflective Telescopes Based on Fusion of Spot Images and Zernike Coefficients

Off-axis reflective telescopes are prone to component misalignment due to external environmental factors and mechanical vibrations. This misalignment introduces low-order aberrations, which severely degrade imaging quality. Thus, active misalignment correction is crucial for maintaining the imaging...
