Plenoptic sensing systems are a type of camera that can capture the multidimensional information of the light field, e.g., capture both the light rays’ intensities and directions. This allows for reconstructing the high-dimensional light fields and supporting various post-capture features such as depth perception, refocusing, synthetic aperture, etc. As the widely used CMOS-based image sensor can only record the intensity of light rays, conventional camera cannot directly capture the multidimensional light field. To address this challenge, a variety of plenoptic sensing systems with specialized hardware and algorithms have been proposed.
