Abstract
An imaging apparatus and corresponding method according to an embodiment of the present invention enables high-resolution, wide-field-of-view, high sensitivity imaging. An embodiment of the invention is a camera system that utilizes motion of an optical element, such as a spatial filtering mask or of the camera itself, to apply different spatial filtering functions to a scene to be imaged. Features of a spatial filtering mask implementing the different filtering functions are adjacent along an axis of the spatial mask, and a pitch of the features of the mask is smaller than a pitch of the sensor elements. An imaging reconstructor having knowledge of the filtering functions can produce a high-resolution image from corresponding low-resolution coded imaging data captured by the imaging system. This approach offers advantages over conventional high-resolution, wide-field imaging, including an ability to use large-pitch, lower cost sensor arrays, and transfer and store much less data.
