Zusammenfassung:Techniques for testing ultrasonic fingerprint sensors include operating a fingerprint impress simulator that may cyclically press a contact pad of the simulator against a platen of an ultrasonic sensor under test. A control electronics arrangement may operate the ultrasonic sensor under test and the fingerprint impress simulator, and may receive ultrasonic image data from the ultrasonic sensor under test. The ultrasonic sensor may include an ultrasonic transmitter and an ultrasonic sensor array disposed between the ultrasonic transmitter and the platen. The control electronics arrangement may cause the ultrasonic transmitter to emit an ultrasonic pulse, and may receive ultrasonic image data from the ultrasonic sensor array, the ultrasonic image data being converted from a detected portion of the ultrasonic pulse.
