ODiSI B Fiber Optic 5.0
The Luna ODiSI B senses temperatures and stress levels using fiber optics in conjunction with a tunable lazer source. The technology consists of distributed optical fibers
that utilize Rayleigh scattering to sense small defects in each fiber's construction. The defects cause a difference in the index of refraction, creating Rayleigh backscattering at the location of these defects. These backscattering profiles are produced using a Mach-Zehnder interferometer. Sensors are alligned along the fibers in an array pattern. Using interference frequencies found from coherent optical frequency domain reflectometry (c-OFDR) technique, the changes in sensor length are then proportional to the frequency created. Sensors are identified based on a keyed profile and when a match is found, the stored spectrum is used as a base spectrum for all other values to measure in the spectrum.
FLIR A655sc Infrared Camera
The FLIR A6xx sc Series Camera is an infrared camera that uses an Uncooled Microbolometer to detect wavelengths within the spectral range of 7.5 - 14.0 µm. The camera has a full window frame rate of 50Hz and a minimum window frame rate of 200Hz. It has a temperature range of –40°C to 150°C and 100°C to 650°C. The FLIR A6xx sc Series camera is used to track points of high and low temperature in order to exploit these points during experiments in the lab.
Thermo Scientific Multi-Gas analyzer Model 60i
The Thermo Scientifi c Multi-Gas analyzer, Model 60i utilizes non-dispersive infrared (NDIR) optical fi lter technology to measure five gases in addition to an oxygen measurement via either chemical cell or paramagnetic technology. CO CO2 NO NO2 SO2 O2. The Model 60i is the only gas analyzer with built-in safeguards to protect the instrument from moisture damage. The 60i utilizes a low sample flow rate that reduces the amount of maintenance due to high particulate and moisture loading on optical surfaces. The analyzer also continuously measures moisture and can shut off the sample pump and activating an alarm before high levels of moisture damage the sensitive components.
