The Luna ODiSI B delivers high speed, fully
distributed strain and temperature
measurements with millimeter spatial resolution.
KEY FEATURES AND PRODUCT HIGHLIGHTS
•
Industry-leading combination of measurement speed,
range and repeatability with extraordinary spatial
resolution

23.8-250 Hz acquisition over entire fiber

Up to 25 Hz active display over 1 meter

Up to 20 meter sensing range

Measurement ranges of ± 10,000 µStrain, -50 to 300 °C

Repeatability of ± 5 µStrain, ± 0.4 °C

As small as 1.25 mm spatial resolution
•
Inexpensive optical fiber sensors
•
Thousands of sensing locations using a single optical
fiber
•
Interrogation of entire fiber and all sensing locations with
a single scan
•
Characterization of both temperature and strain at
different points along a single fiber sensor
The Luna ODiSI B saves time and cost, while adding
new capability to sensing measurements with its
unprecedented combination of high density sensing
and dynamic acquisition over an optical fiber sensor.
The ODiSI B interrogates hundreds of sensing
locations per meter on a single optical fiber
simultaneously at a rate of up to 250 Hz. Reduce cost
and better characterize your system by instrumenting
many sensing locations with an unaltered, inexpensive
optical fiber. With up to 20 meters maximum sensing
length and down to 1.25 mm spatial resolution, the
ODiSI B is the paramount tool for your strain and
temperature sensing applications.

Structural Health Monitoring
The ODiSI B recording the time response of the strain of a cantilever
beam oscillating at its natural frequency. An optical fiber was bonded
to the top surface. The system acquired distributed strain at 100 Hz
with 5 mm sensor spacing.
