Abstract
A task-based imaging system for obtaining data regarding a scene for use in a task includes an image data capturing arrangement for (a) imaging a wavefront of electromagnetic energy from the scene to an intermediate image over a range of spatial frequencies, (b) modifying phase of the wavefront, (c) detecting the intermediate image, and (d) generating image data over the range of spatial frequencies. The task-based imaging system also includes an image data processing arrangement for processing the image data and performing the task. The image data capturing and image data processing arrangements cooperate so that signal-to-noise ratio (SNR) of the task-based imaging system is greater than SNR of the task-based imaging system without phase modification of the wavefront over the range of spatial frequencies.
