Abstract: A hyperspectral sensing device may include an optical collector configured to collect light and to transfer the collected light to a sensor having spectral resolution sufficient for sensing hyperspectral data. In some examples, the sensor comprises a compact spectrometer. The device further comprises a power supply, an electronics module, and an input/output hub enabling the device to transmit acquired data (e.g., to a remote server). In some examples, a plurality of hyperspectral sensing devices are deployed as a network to acquire data over a relatively large area.

Abstract: Spectral analysis system for capturing a spectrum including an inlet opening, a dispersive optical element and reflecting imaging optics having at least one optical functional element defining an optical path from the inlet opening across the dispersive optical element onto an outlet opening and/or detector area of the spectral analysis system and a carrier member defining a flat optical path volume with at least one lateral opening. The dispersive optical element is configured, e.g. in a stationary manner. At least one of the inlet opening, the outlet opening and/or detector area, the at least one optical functional element and the dispersive optical element are integrated in at least one member. The at least one member is mounted on the carrier member at the at least one lateral opening, such that the optical path largely runs transversely to a thickness direction of the optical path volume.

Abstract: The present invention discloses a multichannel broadband high-resolution spectrograph, comprising a plurality of light source incident slits, a multichannel integrated grating, a multichannel shared two-dimensional focus imaging mirror and a two-dimensional area array detector which are sequentially disposed along a light source incident or reflection line, wherein the multichannel integrated grating consists of a plurality of sub-gratings, incident light enters the corresponding integrated gratings along the light source incident slits and then is focused by the shared two-dimensional focus imaging mirror after diffraction of the integrated grating, and diffraction light in a full-spectrum region is incident onto a focal plane of the two-dimensional area array detector for detection. No any mechanical displacement part is disposed, multichannel, full-spectrum and high-speed detection and analysis is achieved, and the present disclosure has high spectrum resolution and working reliability.

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: All-reflective optics for use in imaging spectrometers. In one example, an imaging spectrometer includes an entrance slit and spectrometer optics consisting of a primary mirror, a secondary mirror having a diffraction grating formed thereon, and a tertiary mirror, each of the primary mirror, the secondary mirror, and the tertiary mirror having free-form non-rotationally symmetric surface figures defined by Zernike polynomials. The spectrometer optics are configured to receive the telecentric image at the entrance slit, to disperse the optical radiation into its spectral components to provide dispersed optical radiation, and to focus the dispersed optical radiation onto an image plane positioned in a common plane with the entrance slit. The spectrometer optics have a physical length that is twice the length of the entrance slit, a ratio of a distance of the secondary mirror from the entrance slit to a distance of the primary mirror from the entrance slit being approximately 0.32.

Abstract: A radiation receiving system for an inspection apparatus, used to perform measurements on target structures on lithographic substrates as part of a lithographic process, comprises a spectrometer with a number of inputs. The radiation receiving system comprises: a plurality of inputs, each input being arranged to provide radiation from a target structure; a first optical element operable to receive radiation from each of the plurality of inputs; a second optical element operable to receive radiation from the first optical element and to scatter the radiation; and a third optical element operable to direct the scattered radiation onto a detector. The second optical element may for example be a reflective diffraction grating that diffracts incoming radiation into an output radiation spectrum.
