Abstract
Aspects of this disclosure relate to a biometric sensing device that includes a sensing device and an integrated optical system for authentication. For instance, the sensing device can be an ultrasonic sensing device that can generate an image of a fingerprint and the optical system can transmit light to a finger through the ultrasonic scanning device. In some instances, the acoustic biometric sensing device can generate a liveness parameter associated with a finger based on a reflection of the light.
