In one embodiment, an ultrasonic sensor may include an ultrasonic transmitter configured to transmit an ultrasonic wave, a piezoelectric receiver layer configured to receive a reflected wave of the ultrasonic wave, where the reflected wave comprises a plurality of images of a fingerprint having a plurality of phases in a time sequence, and a platen layer configured to protect the ultrasonic transmitter and the piezoelectric receiver layer. The ultrasonic sensor may further include an ultrasonic sensor array and a processor configured to sum the plurality of images multiplied by a complex phase exponential to form an integrated complex image, align the integrated complex image to a pre-selected phase to form an aligned complex image, determine a maximum energy phase using the aligned complex image, and compute a maximum energy image to represent the fingerprint based at least in part on the aligned complex image at the maximum energy phase."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Correction of diffraction effects in an ultrasonic sensor","description":"Embodiments of correcting diffraction effects in an ultrasonic sensor are disclosed.
