Abstract: An ophthalmic imaging apparatus comprising: an illumination light source and an optical assembly for directing light from the light source into an eye of a subject; a photosensor array comprising a plurality of photosensors positioned for acquiring images of portions of a fundus of the eye; an objective lens positioned along an imaging axis intersecting a point on the fundus of the eye wherein the objective lens is positioned for refracting light that has been reflected by the fundus to form an image of the fundus on an image plane of the objective lens such that the image plane is positioned away from the photosensor array; and a microlens array comprising a plurality of microlenses wherein the microlens array is spaced away from and positioned behind the image plane and wherein the microlens array is positioned in between the image plane and the photosensor array such that each microlens in the array projects a different view of the image formed at the image plane thereby forming an array of elemental image

Abstract: A method of calibration for a plenoptic camera system to determine the true size of an object feature in a light-field image of the object wherein the camera system comprises: an objective lens positioned along an imaging axis intersecting a point in the object; a photosensor positioned for acquiring images of portions of the object and a microlens array positioned in between the objective lens and the photosensor such that each microlens in the array projects a different view of the image formed at the image plane thereby forming an array of elemental images on the photosensor, the method comprising: acquiring an initial image of the object; extracting matching features from any plurality of views derived from a plurality of elemental images forming the initial image; and calculating at least one functional relationship between two or more views having matching features.
