This book was released on 2018-08-18 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from An Assessment of the Backscatter Technique as a Means for Estimating Loss in Optical Waveguides Although the direct method is generally preferred for loss measurements, he backscatter technique has definite advantages in certain applications. Or example, the power level, and loss, in the fiber can be determined as a unction of length. Mode coupling effects may be observed. Regions of high bsorption loss or scattering loss can be identified and located ondestructively as a function of position along the fiber. The fiber does ot need to be cut to determine loss. Another important application is in ield measurements where there is access to only one end of the fiber. Also, his technique provides a convenient way to measure the additional loss due 3 splices and devices inserted into the optical waveguide such as couplers nd connectors.

This book was released on 2018-01-11 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Measurement of Far-Field and Near-Field Radiation Patterns From Optical Fibers The radiation propagating in an optical fiber can take on various spatial and ahquiar distributions depending upon the relative excttation of fiber modes. Usetui information about the fiber can be Obtained by analyzing the radiation exiting an end. This analysis can take place in either the far or nedr-field region of the end. A tar-field measurement determines the angular dependence of intensity (irradiance) sufficiently far from the end of the fiber (fig. 2 whereas, a near-fieio measurement determines the spatiai intensity distribution in the plane of the end fate.

[3] later developed a system which corrected for interference fringe dropouts caused by transient dye laser instabilities Missing fringes were accounted for by comparing numbers counted in an interval with 61 preceding reference interval. Fractional fringes were monitored by measuring the time separation between the first observed dye - laser fringe and the first hene reference-laser fringe. This was done with a signal 100 times faster than the fringe signal rate and the procedure repeated at the end of a scan. The setup was placed in a vacuum chamber and the uncertainty due to dispersion was reported to be with instrument precision on the order of 11108.

This book was released on 2017-10-28 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Measurement of Multimode Optical Fiber Attenuation Details on the two launch conditions are given in section 2. The problems discussed here are not applicable to monomode fibers, where the optical size of the fiber is so small that only a single mode can propagate. Since the strength of intermodal coupling influences the attenuation of the fiber, the environ ment can affect the measured attenuation. The loss value assigned to an uncabled fiber may not be appropriate to the cabled fiber. Likewise, the loss of an uncabled fiber on a spool depends on how tightly the fiber is wrapped around the spool. For purposes of fiber specification for purposes of trade and commerce) it is important that the attenuation assigned to a fiber be of practical use. When fibers are concatenated, the attenuation of the resulting link should be predictable from the specified attenuation of individual fiber sections. That is the crux of the attenuation measurement problem. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
