摘要： A filter array includes optical filters arranged in two dimensions. The optical filters include a first filter and a second filter. The first filter includes a first multimode filter having, within a target wavelength range, first peak wavelengths at each of which the optical transmittance is at a local maximum, and a first band-limiting filter having, as a limiting band, a first sub-wavelength range that is a part of the target wavelength range. The second filter includes a second multimode filter having, within the target wavelength range, second peak wavelengths at each of which the optical transmittance is at a local maximum, at least one of the second peak wavelengths being different from the first peak wavelengths, and a second band-limiting filter restricting transmission of light in a second sub-wavelength range that is a part of the target wavelength range and that is different from the first sub-wavelength range.

摘要： An imaging system includes an imaging apparatus that repeatedly acquires a compressed image in which information regarding light of four or more wavelength bands from a target is compressed, and a processing apparatus. The processing apparatus extracts a partial region including a region of the target from the compressed image so as to compensate for a relative motion between the target and the imaging apparatus, and generates spectral images corresponding to wavelength bands, based on data of the partial region of the compressed image.

摘要： A filter array, which is to be used in a photodetection system that generates image data of each of N wavelength bands (where N is an integer greater than or equal to 4), includes optical filters whose light transmittances in each of the N wavelength bands differ from each other. (σ1/μ1)≥0.1, . . . , and (σN/μN)≥0.1, where μi is a mean value of transmittances, corresponding one-to-one to the optical filters, with respect to light of an i-th wavelength band (where i is an integer greater than or equal to 1 and less than or equal to N) among the N wavelength bands, and where σi is a standard deviation of the transmittances, corresponding one-to-one to the optical filters, with respect to the light of the i-th wavelength band.

摘要： A filter array includes optical filters that are disposed in a two-dimensional plane. At least one optical filter of the optical filters includes an interference layer having a first surface and a second surface opposite the first surface, and a reflective layer provided on the first surface. A transmission spectrum of the at least one optical filter has maximum values. The reflective layer is not provided on the second surface.

摘要： A device used in a system for generating spectral images corresponding to four or more wavelength bands includes optical filters different in spectral transmittance and an image sensor that detects light through the optical filters, in which when the wavelength bands are given numbers in an ascending or descending order of a central wavelength, the image sensor outputs i-th mask data by detecting only light corresponding to an i-th wavelength band and outputs j-th mask data by detecting only light corresponding to a j-th wavelength band among the wavelength bands, a correlation coefficient between the i-th and j-th mask data is greater than or equal to 0.8 in a combination where |i−j| is 1, and is equal to or less than 0.8 in at least one combination where |i−j| is greater than or equal to 2 and less than or equal to N−1.
