A system includes a high density surface emitting laser array source, the high density surface emitting laser array source comprising a near infrared vertical cavity semiconductor laser (VCSEL) array that enables individual access to closely packed laser elements on a sub-microsecond timescale, a detector comprising a dynamic vision sensor having low latency, high dynamic range and ultralow power, and a chip scale neuromorphic computing platform configured to perform real-time target image reconstruction, the distinctly separate high density surface emitting laser array source, the detector and the chip scale neuromorphic computing platform integrated into a single functional whole.

Compact optoelectronic device for noninvasive imaging

A method includes providing an ensemble of distributed sensors, delivering radio frequency (RF) power to each sensor by inductive near-field coupling by a magnetic field projected by an epidermal transmit (Tx) coil, in each individual sensor, detecting a sparse binary event in its immediate environment, reporting the detected sparse binary event to an external RF receiver hub asynchronously and with low latency, and minimizing error rates due to statistical data packet collisions in asynchronous telemetry by digitally encoding each sensor according to a particular address scheme where each address is one function from an infinite set of mathematically orthogonal functions, enabling a simultaneous detection from up to ten thousand points without interference at a common receiver.

Large-scale wireless biosensor networks for biomedical diagnostics

An ultra high-resolution near infrared brain imager system includes a modular cap housing closely spaced multiple vertical-cavity surface-emitting laser-single-photon avalanche photodiode array (VCSEL-SPAD) modules, each one of the VCSEL-SPAD modules including a linear VCSEL array and a SPAD detector.
