General nformation
shows the general information on
the particular sensor, such as its type, the sensor part
number, its serial number and the production tracking
number, the FBG ID.
3.1.2
Calibration Data
The most important information related to the accelerom
eter sensor – the two central wavelengths at room tem
perature and sensitivity - is shown in the Calibration Data
table (number 2 in
used for acceleration computation.
3.1.3
Acceleration Computation
exemplifies the calculations that
should be performed for wavelength measurement to
acceleration conversion. The acceleration variation of an
Accelerometer, under a reference frequency, is given by
the quotient of wavelength shift from the zero moment by
the sensor's sensitivity.
