Abstract
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.
Claims6
An ultra high-resolution near infrared (NIR) brain imager system comprising:
- a modular cap, the modular cap comprising:
- a first array of closely spaced vertical-cavity surface-emitting lasers (VCSELs), each said VCSEL in said array being individually addressable and configured to emit 100 psec NIR pulses, said first array being a two-dimensional array with spacing between VCSELs as low as about 20 μm;
- and
- a second array of single-photon avalanche photodiodes (SPADs), each said SPAD configured to detect said NIR pulses with sub-nanosecond time, each one of the VCSEL-SPAD modules comprising a two-dimensional (2D) VCSEL array and a SPAD detector array;
- and
- wherein said first and second arrays are adapted for multiple input-multiple output (MIMO) communications.
