Multi-channel imaging devices

摘要

A multi-channel imaging device is provided. The multi-channel imaging device comprises a focal plane array comprising an array of pixels configured to detect radiation in a predetermined wavelength band. Subsets of the array of pixels are arranged to define a plurality of unit cell image areas. The multi-channel imaging device also comprises a lens array comprising a plurality of lens elements configured to image a scene onto the plurality of unit cell image areas. The lens elements and the unit cell image areas define a plurality of unit cells comprising at least one lens element and at least one unit cell image area. Each of the plurality of unit cells is configured to create a complete image of the scene. Additionally, a plurality of unit cell filters corresponding to the plurality of unit cells is configured to filter radiation such that each unit cell is dedicated to an image channel is also provided.
