1. A device for spatially resolved photodetection and demodulation of temporally modulated electromagnetic waves, comprising:

  • a one-dimensional or two-dimensional array of pixels (50), each pixel (50) comprising;

    at least two transducer elements (51.1, 51.2) for transducing incident electromagnetic radiation into an electric signal, each transducer element (51.1, 51.2) being associated with;

    at least one storage element (54.1

    54.4) for storing said electric signal, said at least one storage element (54.1

    54.4) being inaccessible or insensitive to incident electromagnetic radiation;

    wherein each pixel (50) comprises an optical element (41) for spatially averaging the electromagnetic radiation incident on the pixel (50) and equally distributing the averaged electromagnetic radiation onto said transducer elements (51.1, 51.2) of the pixel (50).
