Optical Simulation of Lens-Sensor Misalignment Detection Based on Amplitude and Phase of Image

Misalignment between lens and image sensor causes an asymmetric defocus and distortion. We propose a method to detect the misalignment by using the amplitude and phase of image and verify it through an optical simulation.
