Wavefront-coding is a technique in imaging systems that uses signal processing as an integral part of the image capture. In addition, wavefront-coded imaging uses phase elements that must be designed specifically for each application. This combination of an application-phase element and image processing can provide performance that is impossible with traditional imaging systems. In this work we propose the use of Jacobi-Fourier shaped phase masks to produce sharp and clear images for optical systems afflicted by random aberrations, as in imaging through atmospheric turbulence, or retinal imaging through the optics of the eye, among others. |
