    Abstract: The invention may be embodied as an ultrasonic plane wave generator having a first sheet of piezoelectric material and a second sheet of piezoelectric material. A shared electrode may be between the first sheet and the second sheet. A first electrode set may have a plurality of electrodes, and these electrodes may be positioned with respect to the first sheet to form a set of wave generators. A wave generator in this first wave generator set may include the shared electrode, the first sheet, and one of the electrodes in the first electrode set. A second electrode set may have a plurality of electrodes, and these electrodes may be positioned with respect to the second sheet to form another set of wave generators. A wave generator in this second wave generator set may include the shared electrode, the second sheet, and one of the electrodes in the second electrode set.

    Abstract: Methods and systems of determining whether an object is alive, and therefore part of a live individual, are described. An object having an outer surface (e.g. a friction-ridge surface of a finger) and internal parts (e.g. tissue layer, papillae, blood vessels, fat, muscle, nail and bone) is scanned by a system having a transmitter, receiver and computer. One such system has a substantially planar piezoelectric transmit-layer, an ultrasonic receiver array having a plurality of receivers, and a platen. The transmit layer is caused to produce an ultrasound plane-wave traveling toward the object residing on the platen. Using the ultrasonic receiver, ultrasonic energy that has been reflected from the object is detected. The detected ultrasonic energy is analyzed to provide an analysis result, and the analysis result is compared to a template. A determination is made as to whether the analysis result and the template are similar, and the object is declared to be alive if the analysis result is determined to be similar to the template.

    Abstract: Devices and methods of creating an image of a biological object are disclosed. In one embodiment of the invention there is a plane wave ultrasonic pulse generator, an ultrasonic wave manipulation device, an ultrasonic detector and an image generator. In a method according to the invention, a biological object is imaged by emitting an unfocussed ultrasonic energy wave front, reflecting at least a portion of the ultrasonic energy wave front from the object, altering a direction of the ultrasonic energy, detecting that energy, and using the detected energy to create an image of the object.

    Abstract: An ultrasonic reflex imaging device and a method are described. A device according to the invention may include a platen, a generator, and a receiver positioned between the platen and the generator. A backer may be positioned so that the insonification device is between the receiver array and the backer. The backer may be configured to absorb or delay energy that originated from the generator. The generator produces an energy pulse, which travels through the receiver and the platen to reach a biological object. Part of the energy pulse is reflected from the biological object. The reflected energy pulse travels through the platen to the detector. The detector converts the reflect energy pulse to electric signals, which are then interpreted to create an image of the biological object.

    Abstract: This disclosure provides systems, methods and apparatus related to an ultrasonic receiver for detecting ultrasonic energy received at a first surface of the ultrasonic receiver. The ultrasonic receiver includes an array of pixel circuits disposed on a substrate, each pixel circuit in the array including at least one thin film transistor (TFT) element and having a pixel input electrode electrically coupled to the pixel circuit. The ultrasonic receiver is fabricated by forming a piezoelectric layer so as to be in electrical contact with the pixel input electrodes. Forming the piezoelectric layer includes coating a solution containing a polymer onto the array of pixel circuits, crystallizing the polymer to form a crystallized polymer layer and poling the crystallized polymer layer.
