Abstract: Image acquisition apparatuses, spectral apparatuses, methods and storage mediums for use with same are provided herein. At least one apparatus includes: a diffraction element irradiated by a light; a fiber for receiving reflected scattered light from a subject; a diffraction grating dispersing the transmitted light into light fluxes of wavelength bands again; an optical system imaging the split light fluxes; and an imaging device near the focal point of the optical system. An image is changed by rotating the diffraction grating, from which a two-dimensional image is acquired. The transmitted light may be branched into two or more, and input to a collimator lens and imaged as multiple spectral sequences by the optical system. At least one apparatus may form light fluxes traveling at different angles; and may acquire spectral information of the reflected and scattered light. Preferably, for the luminous fluxes, no gap exists in an image.

Abstract: Hyperspectral imaging systems and methods for hyperspectral imaging of scenes in apparent motion are described. 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, without physical or optical reconfiguration of the imaging system, and with no need for moveable mechanical parts. The system achieves high spectral and spatial resolution, is simple, compact, and lightweight, thereby providing an efficient hyperspectral imaging system for aircraft or spaceborne imaging systems.
