RAPID AND PRECISE OPTICALLY MULTIPLEXED IMAGING
First Claim
Patent Images
1. A method of imaging a scene, comprising:
- capturing light from a plurality of regions of the scene in a plurality of channels;
directing each of the plurality of channels onto a focal plane of an image sensor; and
encoding an image formed by one or more of the plurality of channels prior to detection by the image sensor;
wherein encoding of the image is varied by a precise amount over time.

Abstract
Described herein are devices and methods for uniquely encoding one or more channels of an optically multiplexed imaging system rapidly and precisely to improve the system'"'"'s efficiency and performance. The disclosed devices and methods generally provide dynamically variable image encoding that can occur at speeds faster than a capturing frame rate of an image sensor and with a precision that is less than an angular sampling of an image sensor pixel. Such dynamically variable encoding can allow an imaging system to be optimized for use with various scene conditions and sensing objectives, while providing improved efficiency and robustness of disambiguation over prior technologies.
