Description
The si720 is a high power,
high accuracy, high-resolution complement to the Micron
Optics si425. It provides higher
accuracy and resolution than the si425 and can be used for
a wide variety of fiber optic sensors.
The system provides users with a complete
understanding of how the spectral shape of the fiber Bragg
grating sensors react to varying physical conditions - rather
than only reporting shifts in central wavelengths. This
instrument is used both as the first step in the development
of high-volume custom sensing systems and in long term field
measurements.
Applications
-
Useful in the design and selection
of fiber Bragg grating based sensors for strain, temperature,
pressure, etc.
-
High accuracy, resolution and
full profile data provide comprehensive feedback on
fiber Bragg grating and extrinsic Fabry-Perot sensor
capabilities
-
Both built-in and LabVIEW™
peak detection functions provide high resolution, high
accuracy fiber Bragg grating center wavelength measurements
-
Full-spectrum measurements aid
in understanding how sensors' characteristics change
under various physical conditions
-
Useful for analysis of a wide
variety of passive optical sensors - FBGs, Fabry-Perot
sensors, Long Period Gratings, and more
Benefits
-
Two input detection channels
coupled with a powerful and extremely low-noise fiber
ring laser allow simultaneous monitoring of more than
100 sensors per channel
-
Dual-detector design enables
either input channel to measure FBGs in transmission
or reflection
-
System can be quickly adapted
to interrogate many types of sensors
-
Laser is continuously swept across
an 80 nm spectrum at user-selectable rates of 5.0 or
0.5 Hz
-
Automatic calibration is achieved
with every scan using an integrated NIST-traceable absolute
wavelength reference
-
Combination of absolute wavelength
reference and proprietary Micron Optics instrument design
provides a stunning and reliable wavelength repeatability
of 0.05 pm and a wavelength accuracy of 1 pm
-
Fast analog-to-digital conversion
and proprietary LINUX-based software
-
Built-in single board computer,
display and instrument control panel
-
5 Hz data is easily transferred
to PC via Ethernet I/O or through optional GPIB interface
