Plenoptic sensors have been developed as passive method for 3D scanning of a scene by the intensity of the light. In this work a new method to measure 3D, not by its intensity but its wavefront phase, is presented. Microscopy on translucent or fluorescent samples, can take advantage of this technique. Preliminary studies and simulations are presented to show the feasibility of the technique.

The CAFADIS plenoptic camera was mounted onto a Leica M205A stereomicroscope and used as a prototype light field microscope. The ability to generate image stacks focused at different focal planes from a single plenoptic image was demonstrated. The focal stacks were used to create a composite extended focus image and depth map.

The plenoptic camera has been proposed as an alternative wavefront sensor adequate for extended objects within the context of the design of the European Solar Telescope (EST), but it can also be used with point sources. Originated in the field of the Electronic Photography…

ELT laser guide star wavefront sensors are planned to handle an expected amount of data to be overwhelmingly large (1600×1600 pixels at 700 fps). According to the calculations involved, the solutions must consider to run on specialized hardware as Graphical Processing Units (GPUs) or Field Programmable Gate Arrays (FPGAs), among others.
