    Abstract: In a spectroscopic module 1, a flange 7 is formed integrally with a diffraction layer 6 along a periphery thereof so as to become thicker than the diffraction layer 6. As a consequence, at the time of releasing a master mold used for forming the diffraction layer 6 and flange 7, the diffraction layer 6 formed along a convex curved surface 3a of a main unit 3 can be prevented from peeling off from the curved surface 3a together with the master mold. A diffraction grating pattern 9 is formed so as to be eccentric with respect to the center of the diffraction layer 6 toward a predetermined side. Therefore, releasing the mold earlier from the opposite side of the diffraction layer 6 than the predetermined side thereof can prevent the diffraction layer 6 from peeling off and the diffraction grating pattern 9 from being damaged.

    Abstract: Optical radiation from a sample is received by the slit and it is passed through an aperture in a reflective plane of a folding mirror towards a curved reflective surface of a collimating mirror. The slit and the curved reflective surface have a common optical axis. The reflective plane and the curved reflective surface face each other. The optical radiation passed through the folding mirror is collimated by the curved reflective surface. The collimated optical radiation is directed to the reflective plane of the folding mirror by the curved reflective surface. The collimated optical radiation is reflected in a direction other than the common optical axis of the slit and the curved reflective surface by the reflective plane.

    Abstract: The present invention enables snap-shot spectral imaging of a scene at high image generation rates. Light from the scene is processed through an optical system that comprises a coded-aperture. The optical system projects a plurality of images, each characterized by only one of a plurality of spectral components, onto a photodetector array. The plurality of images is interspersed on the photodetector array, but no photodetector receives light characterized by more than one of the plurality of spectral components. As a result, computation of the spatio-spectral datacube that describes the scene is simplified. The present invention, therefore, enables rapid spectral imaging of the scene.
