    Abstract: The spectrometer includes a lightguide substrate, an upper grating layer, a lower grating layer, an image sensor, and a readout circuit. The upper grating layer is disposed on the lightguide substrate and configured to receive a light. The upper grating layer includes a first grating structure, a second grating structure, and a third grating structure, and the first, second, and third grating structures have different grating periods. The lightguide substrate is configured to diffract the light when the light propagates into the lightguide substrate, such that multiple diffraction lights are formed and each of the multiple diffraction lights has different wavelengths and different optical path. The lower grating layer is disposed under the lightguide substrate and configured to emit the multiple diffraction lights. The image sensor is disposed under the lower grating layer. The readout circuit is disposed under the image sensor.

    Abstract: An imaging system is an imaging system using a compressed sensing technology, and includes a filter array including types of filters different from one another in transmission spectrum, an image sensor that generates image data based on light that passes through the filter array, a processing circuit that generates hyperspectral image data including images corresponding to four or more bands included in a target wavelength region on the basis of the image data and a reconstruction table decided on the basis of a spatial distribution of the transmission spectra of the types of filters, and a light source that emits reference light used for calibration for correcting the reconstruction table and having a wavelength of at least one of the four or more bands, and the processing circuit corrects the reconstruction table on the basis of reference image data which the image sensor generates by detecting the reference light.
