    Abstract: A semiconductor detector (100) for electromagnetic radiation within a wavelength range is disclosed, comprising a first waveguide portion (110), a funnel element (130) configured to funnel incident electromagnetic radiation into a first end (112) of the first waveguide portion, and a second waveguide portion (120) extending in parallel with the first waveguide portion. The second waveguide portion is coupled to the first waveguide portion and configured to out-couple electromagnetic radiation from the first waveguide portion, within a sub-range of the wavelength range. Further, a photodetector (140) including a photoactive layer (144) is arranged at a second end (114) of the first waveguide portion and at an end (124) of the second waveguide portion, and configured to separately detect electromagnetic radiation transmitted through and exiting the first waveguide portion and the second waveguide portion.

    Abstract: Example embodiments relate to imaging systems and methods for acquisition of multi-spectral images. One example imaging system includes a detector that includes an array of light sensitive elements arranged in rows and columns. Each light sensitive element is configured to generate a signal dependent on an intensity of light incident onto the light sensitive element. The imaging system also includes a plurality of wavelength separating units. Each wavelength separating unit is configured to spatially separate incident light within a wavelength range into a number of wavelength bands distributed along a line. The line is a straight line. Each wavelength band along the line is associated with a mutually unique light sensitive element. Further, the imaging system includes a processing unit configured to define a number of mutually unique clusters of light sensitive elements for summing signals from the light sensitive elements within the respective clusters.

    Abstract: Example embodiments relate to detectors for detecting electromagnetic radiation. One embodiment includes a detector for detecting electromagnetic radiation spanning a range from a first wavelength to a second wavelength. The detector includes an array of funnel elements for propagating electromagnetic radiation from a second plane towards a first plane. Each of the funnel elements includes an entrance end and an exit end. The entrance ends of the array of funnel elements define the second plane. The entrance end is larger than half of the second wavelength in a medium from which the electromagnetic radiation enters the detector. The exit end is smaller than half of the first wavelength of in the medium. The detector also includes an array of photosensitive elements for detecting electromagnetic radiation incident on the array of photosensitive elements. Each funnel element is associated with a photosensitive element. The array of photosensitive elements defines the first plane.
