Abstract: Exemplary embodiments are directed to a multi-modal biometric analysis system including one or more illumination sources, one or more cameras, and a processing device. The illumination sources are configured to illuminate an iris of a subject. The cameras are configured to capture one or more images of the subject during illumination of the subject with the one or more illumination sources. The images include iris biometric data associated with the iris of the subject and face biometric data associated with a face of the subject. The processing device receives as input the one or more images, analyzes the iris biometric data for iris biometric authenticity, analyzes the face biometric data for face biometric authenticity, and compares the iris biometric data and the face biometric data to determine the biometric authenticity of the subject.

Abstract: A fiber-based optical amplifier is assembled in a compact configuration by utilizing a flexible substrate to support the amplifying fiber as flat coils that are “spun” onto the substrate. The supporting structure for the amplifying fiber is configured to define the minimal acceptable bend radius for the fiber, as well as the maximum diameter that fits within the overall dimensions of the amplifier package. A pressure-sensitive adhesive coating is applied to the flexible substrate to hold the fiber in place. By using a flexible material with an acceptable insulative quality (such as a polyimide), further compactness in the final assembly is achieved by locating the electronics in a space underneath the fiber enclosure.

Abstract: Embodiments of a Z-dimension user-feedback biometric system are provided. In some embodiments, a camera captures subject images positioned along a plurality of Z-dimension positions, including a normal subject image for a mid-range of a capture volume and one or both of the following: (a) a close subject image for a front of the capture volume and (b) a far subject image for a back of the capture volume. In some embodiments, a processing element can be configured to create a normal display image, as well as a close display image (with a first exaggerated quality) and/or a far display image (with a second exaggerated quality). In some embodiments, the first exaggerated quality can be a positive exaggeration of a quality and the second exaggerated quality can be a negative exaggeration of the quality.
