Photolithographic Method for Producing Acoustic Detectors
This technology is a new method to produce hydrophone and acoustic detectors based on the acoustoelectric effect, rather the piezoelectric effect to create an electrical signal. The manufacturing method uses photolithographic techniques, offering finer control of the design and scale of the device. In order to produce detectors or hydrophones for ultrasound...

Method and Apparatus for In-Line Photoacoustic Imaging
This technology is an optical system consisting of a right angle prism, or thin parallel plate, in conjunction with water, an index matching fluid, or some other liquid, that completely reflects acoustic waves to and from an array ultrasound transducer while being optically transparent. The geometry allows simultaneous direct illumination, with high-energy...
