Abstract
A bijective coded aperture system uses mirror system with a multitude of reflector elements attached to an absorbing, such as black, substrate. Each of the reflector elements is independently placed at a different angle with respect to each other in such a manner that the image of the scene is replicated several times at the focal plane and on the image sensor. Moreover, these replicated images may be overlapping. An image processor can then execute reconstruction methods of the image to faithfully represent the scene.
Claims22
A coded aperture imaging system, comprising:
- a mirror system for reflecting light from a scene, the mirror system comprising reflector elements that are positioned at different angles with respect to each other relative to a plane of the mirror system;
- an object lens system for collecting the light from the mirror system;
- and
- an image sensor for detecting the light from the objective lens.
A coded aperture imaging method, comprising:
- reflecting light from a scene with reflector elements that are positioned at different angles with respect to each other relative to a plane of a mirror system;
- collecting the light from the mirror system;
- and
- detecting the collected light.
An imaging system, comprising:
- a mirror system for reflecting light from a scene, the mirror system comprising a MEMS mirror array comprising reflector elements that are positioned at different angles with respect to each other;
- an object lens system for collecting the light from the mirror system;
- and
- an image sensor for detecting the light from the objective lens.
A coded aperture imaging method, comprising:
- detecting light from a known scene through a coded aperture;
- determining a mapping of the aperture using machine learning.
