Product
Overview
This
inertial
angular
rate
sensor
utilizes
the
optical
Sagnac
effect
to
measure
angular
rate
along
its
sensitive
axis.
The
digital
closed-loop
detection
circuit
extracts
optical
path
differences
caused
by
external
angular
rates,
enabling
precise
signal
modulation
and
demodulation
for
accurate
angular
rate
detection.
