Abstract

Disclosed is an apparatus. The apparatus may include an ultrasonic sensor array, a light source system and a control system. Some implementations may include an ultrasonic transmitter. The control system may be operatively configured to control the light source system to emit light that induces acoustic wave emissions inside a target object. The control system may be operatively configured to select a first acquisition time delay for the reception of acoustic wave emissions primarily from a first depth inside the target object. The control system may be operatively configured to acquire firstultrasonic image data from the acoustic wave emissions received by the ultrasonic sensor array during a first acquisition time window. The first acquisition time window may be initiated at an end timeof the first acquisition time delay.

Description

[0001] priority claim [0002] This application claims priority to U.S. Application No. 15 / 149,048, filed May 6, 2016, and entitled "BIOMETRIC SYSTEM WITH PHOTOACOUSTIC IMAGING," which is hereby Incorporated by reference. technical field [0003] The present invention generally relates to biometric devices and methods, including but not limited to biometric devices and methods suitable for mobile devices. Background technique [0004] As mobile devices become more and more multifunctional, user authentication becomes increasingly important. Increasing amounts of personal information can be stored on and / or accessed by mobile devices. Furthermore, mobile devices are increasingly being used to make purchases and perform other business transactions. Some mobile devices, including but not limited to smart phones, currently include fingerprint sensors for user authentication. However, some fingerprint sensors are easily spoofed. Improved authentication methods will be requi...
