This disclosure relates to a time-of-flight sensor including, on a same base substrate, a light emitter configured to emit light into an image scene, a reference sensor configured to detect light emitted by the light emitter, and a signal reception sensor array separated from the light emitter by an optical barrier. The optical barrier is configured to prevent light emitted by the light emitter from directly reaching the signal reception sensor array, with the signal reception sensor array being configured to detect light reflected by the image scene. The reference sensor and the signal reception sensor array are based on semiconductor nanoparticles.

Methods and apparatus for biometric authentication in which two or more cameras are used to capture images of biometric features or aspects for analysis to identify and authenticate a person. An imaging system includes at least two cameras that are used to capture images of a person's iris, eye, periorbital region, and/or other regions of the person's face, and one or more features from the captured images are analyzed to identify and authenticate the person or to detect attempts to spoof the biometric authentication. Information from two or more images may be combined to process aspects and features extracted from the combined images. Alternatively, one of the images to be used for biometric authentication may be determined, for example using one or more objective criteria to evaluate the quality of the captured images.
