Image formation analysis and high resolution image reconstruction for plenoptic imaging systems

, : Image formation analysis and high resolution image reconstruction for plenoptic imaging systems. Applied Optics 52(10): D22-D31

Plenoptic imaging systems are often used for applications like refocusing, multimodal imaging, and multiview imaging. However, their resolution is limited to the number of lenslets. In this paper we investigate paraxial, incoherent, plenoptic image formation, and develop a method to recover some of the resolution for the case of a two-dimensional (2D) in-focus object. This enables the recovery of a conventional-resolution, 2D image from the data captured in a plenoptic system. We show simulation results for a plenoptic system with a known response and Gaussian sensor noise.
