Abstract: The present disclosure describes an optoelectronic system and methods for efficiently capturing three-dimensional data. The optoelectronic system includes a three-dimensional imaging module and a distance measuring module. Data collected via the distance measuring module is used to collect three-dimensional data, such as three-dimensional maps or other representations of three-dimensional objects. Further, the approach can be extended to multiple regions of interest, and can be applied to the acquisition of biometric data.

Abstract: Optoelectronic systems include an array of optoelectronic modules and a computational unit. The array of optoelectronic modules and the computational unit are operable to collect data of a user of the optoelectronic system. The data can be used, for example, to authenticate the identity of the user by being used in multiple user authentication protocols. In some instances, facial recognition data can be augmented with three-dimensional data of the user and can be combined with iris recognition data to authenticate the identity of the user. Such optoelectronic systems can comprise hardware authentication systems external to auxiliary devices such as tablet computers and laptop computers.

Abstract: The present disclosure describes compact remote eye tracking systems that include depth sensing capacity. In one aspect, a method of eye tracking includes illuminating a subject's eye with illumination; detecting, in a depth sensor, optical signals reflected from the subject's face in response to the illumination; generating a depth map based on the optical signals detected by the depth sensor; acquiring an intensity image based on optical signals reflected from the subject's face in response to the illumination; determining, based on a portion of the depth map corresponding to the subject's eye, an estimated distance between the subject's eye and a target screen; determining an estimated gaze direction of the subject's eye based on information obtained from the intensity image; and determining, based on the estimated gaze direction and the estimated distance between the subject's eye and the target screen, a gaze point for the subject's eye.

Abstract: The present disclosure describes cameras having an optical channel that includes spatially separated sensors for sensing different parts of the optical spectrum. For example, in one aspect, an apparatus includes an image sensor module having an optical channel and including a multitude of spatially separated sensors to receive optical signals in the optical channel. The multitude of spatially separated sensors includes a first sensor operable to sense optical signals in a first spectral range, and a second sensor spatially separated from the first sensor and operable to sense optical signals in a second spectral range different from the first spectral range.
