A method for focusing a plenoptic imaging system and an autofocus plenoptic imaging system

摘要

Disclosed is a method for focusing a plenoptic imaging system, the plenoptic imaging system comprising a primary imaging subsystem, a secondary imaging array, and a sensor array, the method comprising: receiving a plenoptic image of an object captured by the sensor array; and adjusting an axial position of the secondary imaging array relative to the primary imaging subsystem, based on increasing a high frequency content in the plenoptic image.
