Plenoptic camera
A plenoptic camera captures not only the intensity of light from a scene but also the direction that light travels. This is achieved using an array of small lenslets placed over its sensor, allowing the camera to record information about various viewpoints in a single image. As a result, users can refocus images after they are taken, create 3D representations, and even change perspectives. This technology has applications in photography, virtual reality, and scientific imaging, providing greater flexibility and depth in visual representation compared to traditional cameras.

A plenoptic camera is a special type of camera that captures not only the intensity of light (like a regular camera) but also the direction from which the light is coming. This allows for unique post-processing capabilities, such as changing the focus after the picture is taken or creating 3D images. By using a microlens array in front of the image sensor, it records a rich set of visual information. This technology enhances photography by providing greater flexibility in how images are viewed and manipulated, enabling innovative applications in fields like virtual reality and scientific imaging.
