and transmitted light. The light typically arrives at normal incident angle
on the grating. The reected intensity is monitored to determine the relative
displacement of the gratings, which resulted from accelerations applied to
the device. Achieved device sensitivities are 590 V G

and noise oors cor-
respond to 17 nG/√Hz (at 1 Hz); the noise oor is the measure of the signal
created from the sum of all the noise sources and undesired signals within
a measurement system.
