Abstract: In one embodiment, a method includes, by an electromagnetic device, emitting optical radiation on one or more objects disposed inside an interior of the electronic device, where the optical radiation is emitted by one or more radiation sources, capturing a set of 2D images of the one or more objects illuminated by the optical radiation, where variation of illumination or of an imaging process permits the set of 2D images to be combined into a representation of the one or more objects, determining whether the set of images comprises a representation of the one or more objects as imaged, in response to determining that the set of images comprises a representation of the one or more objects as imaged, generating a three-dimensional (3D) spectral data cube of the one or more first objects based on spectral information of the first set of images, and storing the 3D spectral data cube for processing by the electronic device.

Abstract: A method of measuring light intensity for imaging using a light detector array comprising a plurality of light detectors arranged to generate an output corresponding to an intensity of incident light. In a first measurement mode the light detector array generates a first plurality of output signals, each generated by one group of proximate light detectors, each group comprising a light detector pair, the first plurality of output signals each corresponding to a difference between the light intensity detected by the light detectors of the group, and generating a light intensity measurement for each group from each received output signal of the first plurality of output signals. In a second measurement mode the light detector array generates a second plurality of output signals, and a light intensity measurement is generated for each light detector from the second plurality of output signals.

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: The invention provides a curved-slit imaging spectrometer, wherein a fiber bundle transfers a straight line image of a front objective lens to a curved slit, and the front objective lens doesn't need to have a curved image plane to directly abut the spectrometer, so that the system is less complicated, and the front objective lens and spectrometer have a simple structure. The arc-shaped or approximately arc-shaped curved slit matches the optimum imaging circle of the Offner-type spectrometer, thereby achieving an extra-long slit. The arced slit is 5 to 10 times longer than the straight slit of the classical Offner-type spectrometer. In the case of a compact size, the length of the slit can be greater than 100 mm. Also, the same spectral response function applies in different fields of view while presenting desirable imaging quality.
