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

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.
