Describes systems or functions that record the entire 4D light field of a space, capturing not just how much light hits a sensor, but the angle at which every ray arrives. Plenoptic cameras typically use a microlens array in front of the sensor to achieve this, allowing an image to be refocused computationally after it is taken.
Heard on the job
The plenoptic sensor lets us reconstruct the 3D position of the particles without needing a second camera.
