METHODS AND APPARATUS HAVING A TWO-SURFACE MICROLENS ARRAY FOR LOW F-NUMBER PLENOPTIC CAMERAS

摘要

Innovations relating to systems for generating plenoptic images, are disclosed. One system includes an objective lens having a focal plane, a light sensor positioned to receive light propagating through the objective lens, a first optical element array positioned between the objective lens and the sensor, the first optical element array including a first plurality of optical elements, and a second optical element array positioned between the first optical element array and the sensor, the second optical element array comprising a second plurality of optical elements. Each optical element of the first optical element array is configured to direct light from a separate portion of an image onto a separate optical element of the second optical element array and wherein each optical element of the second optical element array is configured to project the separate portion of the image of the scene onto a separate location of the sensor.
