Abstract: In a method of operating a two-dimensional array of ultrasonic transducers, a plurality of array positions comprising pluralities of ultrasonic transducers of the two-dimensional array of ultrasonic transducers is defined, the plurality of array positions each comprising a portion of ultrasonic transducers of the two dimensional array of ultrasonic transducers. For each array position of the plurality of array positions, a plurality of ultrasonic transducers associated with the respective array position are activated. The activation includes transmitting ultrasonic signals from a first group of ultrasonic transducers of the plurality of ultrasonic transducers, wherein at least some ultrasonic transducers of the first group of ultrasonic transducers are phase delayed with respect to other ultrasonic transducers of the first group of ultrasonic transducers, the first group of ultrasonic transducers for forming a focused ultrasonic beam. The activation also includes receiving reflected ultrasonic signals at a second group of ultrasonic transducers of the plurality of ultrasonic transducers.

Abstract: A method for generating a composite image having an increased image pixel density by an array of ultrasonic transducers having a given spatial density is provided. The method comprises capturing a first set of pixels at an ultrasonic sensor using a first beamforming pattern, wherein the first beamforming pattern comprises a first pattern of ultrasonic transducers of the ultrasonic sensor. The method further comprises capturing a second set of pixels at the ultrasonic sensor using a second beamforming pattern, wherein the second beamforming pattern comprises a second pattern of ultrasonic transducers. The first beamforming pattern and the second beamforming pattern are different. Pixels of the second set of pixels correspond to positions between pixels of the first set of pixels. The method additionally comprises combining the first and second sets of pixels to form the composite image. An electronic device and a method of generating an image of a fingerprint are also provided.
