    Abstract: Exemplary embodiments provide a tracking optics system for mobile devices. The tracking optics system may comprise a telescope longitudinally disposed in a case of the mobile device, wherein a length of the telescope is greater than a depth of the mobile device; an illuminator that emits a light source and low-power mode through the telescope towards a target of image capture; a two-axis gimbal mirror that is adjusted to steer the light source towards the target until the target is within a field of view of the telescope; and an image sensor that captures an image of the target in response to the illuminator emitting the light source in high power mode to flash the target.

    Abstract: Exemplary embodiments for a biometric camera system for a mobile device, comprise: a near infrared (NIR) light source on the mobile device that flashes a user of the mobile device with near infrared light during image capture; a biometric camera located on the mobile device offset from the NIR light source, the biometric camera comprising: an extended depth of field (EDOF) imaging lens; a bandpass filter located adjacent to the EDOF imaging lens to reject ambient light during image capture; and an imaging sensor located adjacent the bandpass filter that converts an optical image of an object into an electronic signal for image processing; and a processor configured to receive video images of an iris of a user from the image sensor, and attempt to match the video images of the iris with previously registered images stored in an iris database, wherein if a match is found, the user is authenticated.

    Abstract: Using the same image sensor to capture both a two-dimensional (2D) image of a three-dimensional (3D) object and 3D depth measurements for the object. A laser point-scans the surface of the object with light spots, which are detected by a pixel array in the image sensor to generate the 3D depth profile of the object using triangulation. Each row of pixels in the pixel array forms an epipolar line of the corresponding laser scan line. Timestamping provides a correspondence between the pixel location of a captured light spot and the respective scan angle of the laser to remove any ambiguity in triangulation. An Analog-to-Digital Converter (ADC) in the image sensor generates a multi-bit output in the 2D mode and a binary output in the 3D mode to generate timestamps. Strong ambient light is rejected by switching the image sensor to a 3D logarithmic mode from a 3D linear mode.
