REMOTE SENSING OF ATMOSPHERIC COMPOSITION

Atmospheric Remote Sensing Spectrometer

Spectral remote sensing is one of the most important technologies for atmospheric measurements. For these spectrometers, the sun serves as the light source, followed by a camera-based solar tracker. The Atmospheric Processors department derives geophysical atmospheric parameters from remote sensing data. The Resonance GCSO2-3 is the latest UV-sensitive camera that compares images in two spectral bands to produce concentration maps of SO2 plumes. Measurements are made from a variety of locations, platforms, and geometries, including ground-based measurements, aircraft measurements, balloon measurements, and satellite measurements.

Optical Channel Connection of Temperature Sensing Fiber

In this study, we developed a multi-channel fiber-optic temperature sensor system (FTSS) using an optical time-domain reflectometer (OTDR).

Fiber optic sensing technology

Optical fibers can be used as sensors to measure, , and other quantities by modifying a fiber so that the quantity to be measured modulates the,,, or transit time of light in the fiber. Sensors that vary the intensity of light are the simplest, since only a simple source and detector are required.

Fiber Optic Stress Sensing Experiment Strain

In this paper, accuracy calibration experiments and the related analyses of two fiber-optic sensing technologies, the fiber-optic grating (FBG) and optical frequency domain reflectometry (OFDR), are carried out using a standard beam of equal strength and a mature resistive. Abstract: Stress-strain response of optical fibers in direct tension is introduced in this article. Fiber-Bragg-Gratings (FBGs) are used for spot sensing, whereas Rayleigh, Brillouin and Raman scattering are used for distributed sensing in long fibers.

Dutch vibration sensing optical cable

Netherlands-based research centre TNO has developed a method to automatically detect maritime traffic in the vicinity of subsea infrastructure. Using redundant optical fibres in fibre-optic cables as sensors, makes it possible to pick up vibrations from maritime traffic. EIB provides €25 million venture debt financing to Dutch fibre-optic sensor innovator Optics11 for R&D on their technologies for civilian and defence applications. , dark fibers), can be used to monitor vibrations along and over long distances (>100 km) using a Distributed Acoustic Sensing (DAS) interrogator.
