Graphene light-field camera

WebOne-shot 3D cameras available now rely on a micro-lens array to divert the light after it has been focused by the main lens. This array of smaller lenses essentially tears up the picture to recover the directional information from the rays of light, and then the camera’s software reconstructs the image along with the depth information. WebJun 16, 2024 · The light field camera uses an array of tiny “microlenses,” typically (as was the case in Lytro’s design) between the main lens and the film or image sensor. This means multiple two-dimensional...
