Abstract: A four-piece all-aspheric adapter fisheye lens includes a negative meniscus lens, a biconcave lens, a positive meniscus lens, and a biconvex lens. The biconcave lens is between the negative meniscus lens and the positive meniscus lens; the positive meniscus lens is between the biconcave lens and the biconvex lens. The negative meniscus lens, the biconcave lens, the positive meniscus lens, and the biconvex lens are coaxial and arranged with an exit pupil to cooperatively generate an image with a camera lens that has greater field of view than the camera lens alone when the exit pupil is coplanar and coaxial with an entrance pupil of the camera lens. Each of the negative meniscus lens, the biconcave lens, the positive meniscus lens, and the biconvex lens has an aspheric object-side surface and an aspheric image-side surface.

Abstract: An image sensor for imaging fingerprints has multiple photodiode groups each with field of view through a microlens determined by optical characteristics of the microlens and locations of the microlens and openings of upper and lower mask layers. Many photodiode groups have fields of view outwardly splayed from a center-direct field of view. A diameter of openings of the upper mask layer distant from the group having a center-direct field of view is larger than openings of a photodiode group having a center-direct field of view. A method of matching illumination of a group of photodiodes with center-direct field of view to illumination of photodiode groups having outwardly splayed fields of view includes sizing openings in the upper mask layer of photodiode groups with outwardly splayed fields of view larger than openings in the upper mask layer associated with photodiode groups having center-direct field of view.

Abstract: A multiple-lens optical fingerprint reader for reading fingerprints through a display has a spacer; and multiple microlenses with concave and convex surfaces in a microlens array, each microlens of multiple lenses focuses light arriving at that microlens from a finger adjacent the display through the spacer forms an image on associated photosensors on a photosensor array of an image sensor integrated circuit. A method of verifying identity of a user includes illuminating a finger of the user with an OLED display; focusing light from the finger through arrayed microlenses onto a photosensor array, reading the array into overlapping electronic fingerprint images; extracting features from the overlapping fingerprint images or from a stitched fingerprint image, and comparing the features to features of at least one user in a library of features and associated with one or more fingers of one or more authorized users.
