Marine plankton microscope system based on light field camera

摘要

Light Field camera is a kind of device which uses a microlens array to record the four-dimensional light field information in the scene and matches the light with the CCD to realize the function of image refocusing according to given relationship. In this paper, we apply the microlens array in the underwater microscopy system and use microscopic objective, microlens array and CCD to construct an underwater light field microscope. We improve microscopy system which has small depth and is difficult to focus and evaluate effect of microlens array on light field sampling and resolution of refocused images at different positions. In the experiments, we calibrate camera, confirm the magnification and field size and take some photos of marine plankton in the experimental environment.
