More specifically, we combined the frequency-domain NIRS . Intrinsic sensing techniques such as those that use fiber Bragg gratings (FBGs) allow the strain and temperature at many points along a single optical fiber to be measured, opening up the possibility of extensive FOS networks. Intensity measurements are the easiest to perform though they may not be as sensitive to interferometric techniques, where a reference path is compared to a test path and the interferrence pattern due to a phase shift is measured. Fiber Optic Measurement Techniques. Use of a laryngeal mask (LMA) as a conduit for fiberoptic-aided tracheal intubation when unanticipated airway difficulty is encountered has been previously reported. A suitable target reflectivity Although several sensing techniques have been described in the literature, POFs are best suited for intensiometric sensors, which are sensors that exploit the variation of the received light intensity with the quantity under measurement. In-situ fiber tapering for SCG consists of coupling the pump source through the fiber to be tapered to a spectral measurement device. By this book you get a knowledge on optical sources(LEDs, LASERs), Optical Fiber ,Optical amplifier etc. Posted by mahmud anik at 11:33:00 PM · Email ThisBlogThis! To keep the overall costs low, the sensor uses plastic optical fibers and an intensiometric approach based on the received light intensity after the reflection from the target whose displacement has to be measured.

If detector gains need to be changed, or source and detector fibers need to be disconnected during measurements, repeat the calibration procedure of the FDNIRS device. We investigated the possibility of using more sophisticated NIRS optical methods to quantify cerebral oxygen metabolism at the bedside in healthy and brain-injured newborns.
