TECHNOLOGY

The performance improvement is attributable
to joint optimization of system-level architecture,
circuits, and signaling schemes for the implementation.
Such as, high-SNR fNIRS system
with high signal-to-noise ratio (SNR) receivers,
a modulation scheme,
and a multi-input-multi-output- (MIMO-)
based data extraction algorithm.
The multi-channel receivers are implemented
in a single IC to decrease system size for portability.

01

INTEGRATED CIRCUITS (IC)

IC contains high-SNR receivers and
power & pattern controllable transmitters

02

SMALL OPTICAL ELEMENTS

Eliminate optical fibers for portability.
The shape of emitting light
from LASER is more collimated than LED.
The spectral density of LASER is more accurate
than LED.

03

MULTI-INPUT MULTI-OUTPUT (MIMO)

By using modulation scheme,
NIRSIT can monitor multi-channel of brain information in continuously.

04

DIFFUSE OPTICAL TOMOGRAPHY (DOT)

DOT estimates spatial distribution of absorption
characteristics of brain in 3D structure
with fine spatial resolution.
