Abstract: A microscale photoacoustic sensor uses the detection of ultrasound waves generated by a sample in response to incident light absorption to perform photoacoustic spectroscopy, imaging, and microscopy. The microscale photoacoustic sensor, including components to excite a sample and detect ultrasound waves, may be integrated onto a single chip. The microscale photoacoustic sensor may excite a sample using a metasurface collimator. The metasurface collimator includes an array of diffraction grooves to collimate an excitation beam uniformly out of the plane of the sensor to create a wide and homogeneous beam spot. The microscale photoacoustic sensor may detect ultrasound waves using an optical photoacoustic transducer. The optical photoacoustic transducer includes a resonator on a mechanical membrane to detect ultrasound waves with high sensitivity. The microscale photoacoustic sensor may be used in applications such as deep-tissue neural imaging or microfluidic biological screening.

The integrated wiring provides an interface for solar cells having back side electrical contacts. The single side contacts enable the use of pick and place (PnP) technology in manufacturing the space-grade solar array. The solar cell is easily and efficiently packaged and electrically interconnected with other solar cells on a solar panel such as by using PnP process. The back side contacts are matched from a size and positioning standpoint to corresponding contacts on the printed circuit board.

Abstract: A system and method for image reconstruction for non-contact ultrasound is provided, where maps or ultrasound images of a subject may be generated without physically contacting the subject. Adjusting or optimizing the photoacoustic excitation system may be performed, such as with beam shaping, surface modifications, or closed-loop automated adjustments. 2D and/or 3D spatial locations of source and receiver laser spots may be used to provide a spatial reference location for ultrasound image reconstruction in a clinically efficacious manner. In addition, point tracking, surface profile characterization, laser adjustments, and/or surface enhancements may be used to facilitate image reconstruction of the subject.
