White light emitting colimu00e1vel ultra low coherence

摘要

White light emitting colimu00e1vel ultra low coherence. Utility model patent for a device comprising light emitting white colimu00e1vel and low consistency. The device is comprised by two sets of optical fibers, a and B, coupled optically and glued with epoxy EPO Tek 32 301 - 2.The kit is composed of a segment of optical fiber 1, 15 mm in length to 200 microns in diameter core, 20 microns thick cladding and 20 microns thick buffer polyamide, encapsulated in a jacket of polyamide 2, subsequently, a jacket of steel 3 and finalm Being inserted partially in a jacket of epoxy 4 with both ends polished.The set B is composed of 7 segments of the optical fibers 5, 80 mm in length, 50 microns diameter core, 10 microns thick cladding and 10 microns thick buffer polyamide, all with one of the ends grouped and inserted in a single jacket of polyamide 6, subsequ00fc Often a single jacket of steel 7 and finally inserted on a totally epoxy jacket 8.This end, polished, and optically aligned with the set to the side inserted in the jacket of epoxy of the latter. This coupling is secured by gluing with EPO Tek 32 30 1 - 2.Each of the ends of the optical fibers loose seven 9 is inserted individually in the jackets of steel 10, and these ends polished and finally each inserted into an LED 11, (English acronym for the description of the device light emitting diode), a specific color to pr. u00f3ximo point of light emission and glued with EPO Tek 32 30 1 - 2.For the seven optical fibers are used seven LEDs with seven different colors covering nearly the whole visible optical spectrum.All this set is sealed and sealed in a tube of anodized aluminum 12, in a dark color with black epoxy excepting the end composed of the electric terminals of the LEDs 13, and the tip of the optical fiber of the whole external jacket of epoxy coupled optically to a glass plate o Ptico transparent coating 14, with air on both sides.In accordance with the optical characteristics presented by this device, during the testing and the basic experiments, it can be used in strategic applications such as construction of gyros for drive of missiles and aircraft, octpara non-invasive tomography analysis of OL Hos...Teeth and skin and other applications where the operational base is based on the analysis interferomu00e9trica with light sources with a length of coherence below 1 sym, covering the whole visible region of the spectrum of light.Having length of coherence of up to 500 nanometers, i.e. 0.5 sym, its efficiency can be higher than the device currently effective for the applications in question, having the advantage of not being very sensitive to electrostatic discharges and can be constructed in a The wide range of spectral range, considering all the LEDs are available in the market.In addition, the segments of the optical fibers used may be rearranged to different diameters so as to compose a greater or lesser number of fibres or achieve the reduction of the diameter of the segment of the optical fiber used in the output of the device.
