Recently, a novel light field PIV technique that has less complexity of calibration is proposed. Light field camera uses a dense microlens array mounted in the vicinity of a sensor to record the spatial and angular distribution of light entering the camera. Using light field camera, the depth information of particles can be recovered by single camera that enables to develop a novel 3D3C PIV technique. The paper firstly demonstrates the volumetric reconstruction of particulate fields from a light field image using reconstruction technique called MART. The effects of the light field optics on effective spatial resolution, reconstruction quality are discussed.
