Patent ID: 7060957

Claim:
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 ).
