Abstract
In order to improve the imaging quality, modern optical system often adopts the method of increasing the number of lenses or introducing aspherical lens to reduce the aberration, which makes the optical and mechanical structure of the imaging system more complex, the installation and adjustment technology stricter. This paper introduces the computational optics technology, uses a single lens as a photographic lens, selects the field programmable logical array as the core controller, and realizes an online computational imaging system. It reduces the number of optical elements and the hardware complexity of the system. The super laplacian algorithm is adopted in the host computer to overcome image degradation caused by image difference of a single-lens imaging system, calculation and restore of the original clear image are also realized, and the recovery time is shortened from several minutes to several seconds, which effectively improves the real-time performance of a single-lens computational imaging system.
