Dynamic Adjustment of Multimode Lightfield Imaging System Using Exposure Condition and Filter Position

摘要

An adjustable multimode lightfield imaging system. A non-homogeneous filter module is positioned at the pupil plane of the lightfield imaging system and provides the multimode capability. The filter module can be moved relative to the imaging system with the exposure conditions adjusted accordingly, thus allowing adjustment of the multimode capability.

主权项

1. An adjustable multimode lightfield imaging system comprising:
an optical module that forms an optical image of an object, the optical module characterized by imaging optics, a pupil plane and an image plane; a filter array positioned approximately at the pupil plane, the filter array moveable relative to the optical module; an array of micro-imaging elements positioned approximately at the image plane; a detector array positioned such that the micro-imaging elements image the filter array onto the detector array, the detector array capturing a multimode image of the object according to an exposure condition; and a controller that adjusts the exposure condition in response to a position of the filter array.
