Imaging systems and methods for imaging of scenes in apparent motion are described. A multi-axis positioning mechanism is operable to move an area imaging device along a tracking axis. A control module directs the multi-axis positioning mechanism to set the tracking axis to be substantially parallel with the apparent motion, and directs the multi-axis positioning mechanism to move the area imaging device in one or more cycles such that the area imaging device moves, in each of the one or more cycles, forward along the tracking axis at a tracking speed that compensates for the apparent motion. The control module directs the area imaging device to take at least one exposure during each of the one or more cycles to generate one or more exposures. An imaging module forms an image of the scene based on the one or more exposures.

FOCUS PLANE EQUALIZER APPARATUS WITH PRISMATIC FOCUS CORRECTOR
Systems and methods for hyperspectral and multispectral imaging are disclosed. A system includes a lens and an imaging device having a plurality of pixel sensors. A focus corrector is located within the optical path to refract at least a portion of the incoming light and change the focusing distance of specific wavelengths of light to converge at a focal plane. The focal corrector is selected based upon the imaging system to reduce an overall measure of deviation between a focal length curve for the lens and a focus position curve for pixel sensors to produce focused imaging data for a broad spectrum of light, including beyond the visible range.

HYPER-SPECTRAL IMAGING WHEN OBSERVED OBJECT IS STILL
A hyperspectral imaging systems includes an imaging sensor, a multispectral filter, and an actuator. The actuator moves the multispectral filter with respect to the imaging sensor to capture a scene with full spectral data. The spectral data of the scene can be stored in a hyperspectral data cube, which can be compressed, processed, stored, and/or sent to a remote location. Each acquired image includes a spatial map of the scene which facilitates pointing, focusing, and data analysis. The spectral measurement parameters can be configured dynamically in order to optimize performance such as spectral resolution, storage capacity, and transmission bandwidth. The system achieves high spectral and spatial resolution, is simple, compact, and lightweight, thereby providing an efficient hyperspectral imaging system.

A smart satellite system is capable of decision making and prioritization on the fly to optimize the use of downlink bandwidth to deliver prioritized data based upon opportunity and the resources of available payloads. By providing a satellite system with substantial processing power and a level of autonomy, the satellite is able to make decisions about capturing imagery data, including image data processing, object detection, image segmentation, and re-orientation of the satellite based upon the opportunity, from the satellite's perspective, for capturing image data of areas or objects of interest. Through the use of machine learning and in-orbit image analysis, the satellite may transmit only a subset of the captured images, portions of the captured images, or the result of image analysis, thereby efficiently using the downlink communication channel.
