This book was released on 2012-12-06 with total page 852 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fibre Optics has gained prominence in: telecommunications, data transmission and distribution, cable television networks, sensing and control, light probing and instrumentation. The 1990's shows an increased expansion of optical fibre networks which respond to the rapid growth on a world scale of long distance trunk lines combined with a family of emerging optical based services in which fibre-to-the-home will have the greatest impact. There is already evidence that optical communications are moving toward higher bit-rates, wavelength transparency and irrelevance of signal formats. The rate of change in fibre optics and the emergence of new services will be a mere consequence of economics. The actual increasing of cost and the demand for high-date-rates or large bandwidth per transmission channels, and the lack of available space in the congested conduits in urban areas, strongly favour the technological change to fibre optics. The recognised advantages of fibre optic technologies and the unchallenged potential to respond to future needs requires the inclusion of fibre optics networking into new installations. Concomitantly, current progress in the field of optical fibres (optical fibre amplifiers, optical fibre switching, WDM, fibre gratings, etc.) unfold major technical advances and greater flexibility in the designs and engineering of networks, optical fibre components and instrumentation. The explosion of growth in fibre sensors, fibre probes and the myriad of fibre based components shows that we are only using a fraction of optical fibre potential.

Download or read book Applications of High Resolution and Accuracy Frequency Modulated Continuous Wave LADAR written by Ana Baselga Mateo and published by . This book was released on 2014 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high resolution frequency modulated continuous wave (FMCW) laser and detection ranging (LADAR) system developed by Spectrum Lab and Bridger Photonics Inc. could be potentially used for volume metrology purposes. However, comparisons with other length metrology methods would help to determine its actual precision and accuracy. An ultra-low phase noise and narrow bandwidth laser centered at 1536nm is used to build a displacement tracking interferometer for comparisons. Lock-in detection based on phase modulation is used to reduce sensitivity to amplitude noise. The data is processed to obtain an accurate displacement measurement with a novel fringe counting technique that provides resolution higher than lambda/4. After calibrating and figuring out the stability of the FMCW LADAR, its ranging capability is determined by comparison with these results along different wavelength regions. Furthermore, we propose a combination of the trilateration techniques with the FMCW LADAR system for accurate 2D metrology. This idea is developed from design to implementation stages. Surface profiles of non-cooperative diffuse targets using lasers sources with different optical bandwidths are presented. A photon budget and an error analysis of the experimental results are also included.
