    Abstract: A photodetection device including an image sensor that includes fifth pixels and sixth pixels; an interference element that includes fifth incident regions; and illumination that emits light in a first wavelength band and a second wavelength band. The interference element causes first interference of light in the first wavelength band incident on two fifth incident regions, and guides resultant light of the first interference to any of the fifth pixels and guides another part of the light in the first wavelength band to any of the sixth pixels, and causes second interference of part of the light in the second wavelength band incident on the two fifth incident regions, and guides resultant light of the second interference to any of the fifth pixels and guides another part of the light in the second wavelength band incident on the two fifth incident regions to any of the sixth pixels.

    Abstract: A non-paraxial Talbot spectrometer includes a transmission grating to receive incident light. The grating period of the transmission grating is comparable to the wavelength of interest so as to allow the Talbot spectrometer to operate outside the paraxial limit. Light transmitted through the transmission grating forms periodic Talbot images. A tilted detector is employed to simultaneously sample the Talbot images at various distances along a direction perpendicular to the grating. Spectral information of the incident light can be calculated by taking Fourier transform of the measured Talbot images or by comparing the measured Talbot images with a library of intensity patterns acquired with light sources having known wavelengths.

    Abstract: An interferometer wherein an incident beam from a radiation source hits a beam splitter at a first oblique angle of incidence and is split into a first, reflected partial beam, and a second, transmitted partial beam, that subsequently travel along separate arms of the interferometer. The first and second partial beams are respectively intercepted, reflected, and re-split to form returning beam portions and reflected and transmitted exit beam portions. A second terminal mirror and a folding mirror, which intercepts the second partial beam at a second oblique angle of incidence, are associated with the second interferometer arm and positioned orthogonal to the reference plane and on opposite sides of the exit path, so that a section of the second partial beam from the folding mirror to the terminal mirror and back to the folding mirror crosses the exit beam twice.

    Abstract: An interferometer is disclosed, such as may be incorporated into a hand-held spectrometer. The interferometer comprises enclosed path optics and a detector, the enclosed path optics comprise at least two reflecting elements and a beamsplitter, the beamsplitter is arranged to divide an input beam into first and second beams. The enclosed path optics are arranged to direct the first and second beams in opposite directions around paths enclosing an area and to output the first and second beams towards the detector. The enclosed path optics also focus the first and second beams onto the detector. The detector is arranged to detect a pattern produced by interference of the first and second beams. In a preferred embodiment the two reflecting elements are a pair of concave mirrors, and the enclosed path optics enclose a triangular area. The use of concave mirrors for both reflection and focussing provides the interferometer with compactness.
