Abstract
An ultrasonic holography imaging system and method are provided. The ultrasonic holography imaging system includes an ultrasonic transducer array coupled to an analog processing section. The analog processing section is coupled to a digital processing section. The digital processing section generates digital signals to be converted by the analog processing section into analog signals that are transmitted to individual transceiver elements within the ultrasonic transducer array to cause separate ones of the individual transceiver elements to emit ultrasonic waveforms that are differentiated from each other by one or more parameters, including amplitude, frequency, and phase or modulation thereof.
Claims11
An ultrasonic holography imaging system comprising:
- an ultrasonic transducer array including a plurality of transceiver elements configured to emit a plurality of ultrasonic waveforms toward a physical item, and receive a plurality of return ultrasonic waveforms reflected from the physical item;
- and
- a processor system coupled to the ultrasonic transducer array and a memory device, the processor system configured to:
- define an image structure using data stored in the memory device, the data representing a geometry of the physical item, wherein the defined image structure corresponds to an array of points in space as target points for the plurality of ultrasonic waveforms;
- and
- generate a plurality of outgoing analog transceiver driving signals configured to cause the ultrasonic transducer array to emit the plurality of ultrasonic waveforms to form an ultrasonic pulse field having a shape based at least in part on the defined image structure, wherein at least two of the plurality of ultrasonic waveforms are differentiated from each other through variation of at least one of amplitude and frequency.
