According to an aspect of the present inventive concept there is provided a device for polarization dependent imaging, comprising a detector comprising an array of light sensitive elements; a plurality of light propagating units, each comprising: a funnel element having a collecting end and a transmitting end, the funnel element being configured to collect light at the collecting end and propagate the light to the transmitting end; a waveguide having a receiving end and a distributing end, the waveguide being configured to receive the light from the transmitting end at the receiving end and propagate the light to the distributing end, wherein the waveguide is configured to propagate the light through the waveguide in dependence of polarization such that a distribution of the light at different locations of the distributing end is dependent on polarization of the light.

Device and a method for polarization dependent imaging

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.

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.
