    摘要： A multimode fundus camera enables three-dimensional and/or spectral/polarization imaging of the interior of the eye to assist in improved diagnosis. In one aspect, the multimode fundus camera includes a first imaging subsystem, a filter module, and a second imaging subsystem. The first imaging subsystem is positionable in front of an eye to form an optical image of an interior of the eye. The filter module is positioned at a pupil plane of the first imaging subsystem or at a conjugate thereof. The second imaging subsystem include a microimaging array and a sensor array. The microimaging array is positioned at the image plane or a conjugate thereof, and the sensor array is positioned at the pupil plane or a conjugate thereof.

    摘要： A collimated object is adjustable to produce collimated light propagating along different propagation directions. The plenoptic imaging system under calibration captures plenoptic images of the object adjusted to different propagation directions. The captured plenoptic images includes superpixels, each of which includes subpixels. Each subpixel captures light from a corresponding light field viewing direction. Based on the captured plenoptic images, a calibration module calculates which propagation directions map to which subpixels. The mapping defines the light field viewing directions for the subpixels. This can be used to improve processing of plenoptic images captured by the plenoptic imaging system.
