A light field camera comprising: a micro photo-detector array device having a light detection surface defining an array of pixels, each pixel being a light detector that is individually addressable to output an electrical signal responsive to the intensity of light coupled into an aperture of the respective pixel; and a micro lens array of micro lens elements; the micro photo-detector array device and the micro lens array being assembled together as a single assembly characterized by: means (620, 635, 636; 720) for temporally angularly articulating the assembly about at least one axis parallel to a plane of the light detection surface of the micro photo-detector array device and at least through a maximum articulation angle; said means for temporally angularly articulating being so configured that the periodicity of the temporal angular articulation enables temporal coverage of the maximum articulation angle within an image frame capture duration; each micro lens element of the micro lens array being associated and aligned relative to a plurality of pixels within a respective two dimensional pixel group array of the micro photo-detector array device, with each lens optically mapping light that impinges an aperture of the respective lens from a discrete set of directions within a light field defined by an angular extent of the respective lens onto the corresponding plurality of pixels within the two dimensional array of pixel groups (G i) of the micro photo-detector array device, the discrete set of directions defining an angular resolution between adjacent directions and an angular extent of the set of light directions; whereby the temporal angular articulation about the at least one axis expands the angular extent and/or the angular resolution in a direction about the axis of the angular articulation. a micro photo-detector array device having a light detection surface defining an array of pixels, each pixel being a light detector that is individually addressable to output an electrical signal responsive to the intensity of light coupled into an aperture of the respective pixel; and a micro lens array of micro lens elements; the micro photo-detector array device and the micro lens array being assembled together as a single assembly characterized by: means (620, 635, 636; 720) for temporally angularly articulating the assembly about at least one axis parallel to a plane of the light detection surface of the micro photo-detector array device and at least through a maximum articulation angle; said means for temporally angularly articulating being so configured that the periodicity of the temporal angular articulation enables temporal coverage of the maximum articulation angle within an image frame capture duration; each micro lens element of the micro lens array being associated and aligned relative to a plurality of pixels within a respective two dimensional pixel group array of the micro photo-detector array device, with each lens optically mapping light that impinges an aperture of the respective lens from a discrete set of directions within a light field defined by an angular extent of the respective lens onto the corresponding plurality of pixels within the two dimensional array of pixel groups (G i) of the micro photo-detector array device, the discrete set of directions defining an angular resolution between adjacent directions and an angular extent of the set of light directions; whereby the temporal angular articulation about the at least one axis expands the angular extent and/or the angular resolution in a direction about the axis of the angular articulation. means (620, 635, 636; 720) for temporally angularly articulating the assembly about at least one axis parallel to a plane of the light detection surface of the micro photo-detector array device and at least through a maximum articulation angle; said means for temporally angularly articulating being so configured that the periodicity of the temporal angular articulation enables temporal coverage of the maximum articulation angle within an image frame capture duration; each micro lens element of the micro lens array being associated and aligned relative to a plurality of pixels within a respective two dimensional pixel group array of the micro photo-detector array device, with each lens optically mapping light that impinges an aperture of the respective lens from a discrete set of directions within a light field defined by an angular extent of the respective lens onto the corresponding plurality of pixels within the two dimensional array of pixel groups (G i) of the micro photo-detector array device, the discrete set of directions defining an angular resolution between adjacent directions and an angular extent of the set of light directions; whereby the temporal angular articulation about the at least one axis expands the angular extent and/or the angular resolution in a direction about the axis of the angular articulation.
