“…After deriving the PSFs/OTFs, it is necessary to characterize their consistency to aberrations using a variety of metrics. The invariance of the PSF to aberrations can be characterized by Strehl ratio 89 , Fisher information 89,97 , mean square error 26,90,96,102 , and variance 103 . The consistency of MTF/OTF to aberrations can be characterized by Fisher information 64,72,73,85 , mean square error 74,80 , Hilbert space angle 68,69,72,76 , and standard deviation 104 .…”

“…Another way to mitigate optical aberrations operates by adding masks to the optical system to encode the wavefront, including amplitude masks [12,13] and phase masks [14][15][16]. However, amplitude masks can block a portion of the incident light, and very fine printing patterns can cause diffraction artifacts [12].…”

The image deconvolution technique can recover potential sharp images from blurred images affected by aberrations. Obtaining the point spread function (PSF) of the imaging system accurately is a prerequisite for robust deconvolution. In this paper, a computational imaging method based on wavefront coding is proposed to reconstruct the wavefront aberration of a photographic system. Firstly, a group of images affected by local aberration is obtained by applying wavefront coding on the optical system’s spectral plane. Then, the PSF is recovered accurately by pupil function synthesis, and finally, the aberration-affected images are recovered by image deconvolution. After aberration correction, the image’s coefficient of variation and mean relative deviation are improved by 60% and 30%, respectively, and the image can reach the limit of resolution of the sensor, as proved by the resolution test board. Meanwhile, the method’s robust anti-noise capability is confirmed through simulation experiments. Through the conversion of the complexity of optical design to a post-processing algorithm, this method offers an economical and efficient strategy for obtaining high-resolution and high-quality images using a simple large-field lens.
