    Abstract: A broadband area-division beamsplitter that includes a pair of abutting triangular prisms providing two surfaces that are in optical contact in certain areas and are out of optical contact in other areas. One prism surface is substantially planar while adjoining surface of the other prism has alternating protrusions and depressions. The protrusions contact the substantially planar surface to form an optically continuous medium for light transmission. The depressions do not contact the planar surface forming gaps. The two surfaces are oriented on a diagonal so that light incident through one of the other prism faces is incident on the adjoining surfaces at an angle larger than the critical angle, providing total internal reflection at the out-of-contact gap regions. The protrusions and depressions on the one prism surface may be in the form of a corrugation or a checkerboard or some other patterns. The reticulation size of the pattern may be less than about 10 .mu.m , so that light diffracted from the beamsplitter will fall outside of the apertures of optical systems in which the beamsplitter is used.

    Abstract: A hyperspectral imaging device (100) is provided comprising an input (102) for receiving a light field from a scene (106), an encoder (108), at least one dispersive element (110, 112), at least one array detector (114, 110) and a processor (118). The encoder (108) is arranged to receive at least a portion of the light field from the input (102) and transform it to provide a first and second encoded light (120, 122) field having different spatial patterns. At least one dispersive element (110, 112) is arranged to apply spectral shear to the first and second encoded light fields (120, 122) respectively to provide first and second sheared light fields (124, 126). At least one array detector (114, 116) is arranged to detect the first and second sheared light fields (124, 126). The processor (118) is arranged to process an output from the at least one array detector (114, 116) to determine a datacube (128) corresponding to a hyperspectral image of the scene.

    Abstract: A technology is described for hyperspectral imaging. An example of the technology can include receiving an event stream of events from an event camera coupled to an interferometer. The event camera can receive light output from the interferometer and generate the event stream, comprising event data that corresponds to the light output. The events in the event stream can indicate a pixel that detected an event, a time of the event, and a polarity of change in brightness detected by the pixel. Spectral data can be generated for the events in the event stream using a demodulation and frequency transform to convert temporospatial aggregates of events in the event stream to frequency domain data that corresponds to an optical spectrum. A hyperspectral image of an input scene in a spectral range can be generated using the spectral data.

    Abstract: A double-channel miniaturized Raman spectrometer includes a sequentially-connected near-infrared laser diode or near-ultraviolet laser emitter, a collimated laser beam expander, a first beam splitter that retards laser light but penetrates laser light and Raman light, a cylindrical or spherical objective lens with or without zooming, a second beam splitter that retards laser light but penetrates Raman light, a relay optical system, a slit, two spectral lens, a plurality of line-array or matrix-array CCD or CMOS detectors, a GPS, and a data processing and wireless transceiver system. After the laser channel photographing a target and aligning an optical axis and a Raman channel to measure the sample, the data is wirelessly sent to a cell phone and a cloud computer for spectrum separation, peak search, spectral library establishment, material identification and the like in order to obtain a quick conclusion.

    Abstract: An optical characteristic measuring apparatus includes an optical system, a detector, and an analysis unit. The optical system collects detection light incident from a sample. The detector spectrally disperses the detection light in plural times to generate plural pieces of detection data, the plural pieces of detection data indicating their respective spectra of detection light incident from the sample to the optical system with an optical distance between the sample and the optical system being different from each other. The analysis unit analyzes the spectrum indicated by the detection data to measure a predetermined optical characteristic of the sample. The analysis unit specifies a piece of the detection data to be used for measuring the optical characteristic based on intensity of the detection light in the plural pieces of detection data, and measures the optical characteristic based on the specified piece of the detection data.
