Several kinds of micro optics array have been developed to form aerial images in the mid‐air, and we propose evaluation methods for imaging performance of the optical system using the micro optics array. To evaluate the influence caused by aperture limitation of micro optics array and diffraction, the MTF measurement method using a knife edge has been improved considering the viewing direction/angle...
Film-based cameras were replaced with digital cameras in a very short period. Saving film costs for each shot is not only of advantage of this transition. The more important advantage by this digitization is that forming optically a completed image on detector is not necessary and acquired data are processable by a computer. We can think that, with optional optical system-lens array-, acquired data...
Light-field optics is a novel system in which image is exchangeable in between 2D (light-field data) and real 3D, although this technology is well known just for refocusing camera
Recently, light field cameras have become popular as cameras with which you can refocus images after having taken pictures. In this paper I report that combination of this light field camera and integral display has useful features for 3D image capture and reconstruction. Refocusing function is based on 3D information contained in light field data and this fact means that a light field camera captures...
