The refraction of light in two slightly different directions to form two rays; the phenomenon can be used to locate stress in a transparent material. BIT Binary Digit. The smallest unit of data (and most basic) for data communications. It can have a value of a one (mark) or a zero (...
LCD Billhead Shark LED searchlight has an excellent optic beam 2-3deg, with mostly laser light rays and long range of up to 3000 meters. LCD searchlights are suitable for all ocean-going and inland-waterway vessels - typical examples being merchant ves...
Figure 7.2: Bending of light rays. Snell's Law How optical fibers work can be explained by Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the propagation velocities of the wave in the tw...
In optical fiber, mode describes the propagation of light rays in an optical fiber. Optical fiber supports many modes of propagation, depending on the size of the fiber. When the core has a diameter that is large compared to the wavelength of the light signal, many modes of light are ...
15678/62. Class 40 (2). A Kerr record for use with apparatus such as described in Specification 883,936, comprises a base 12, successively coated in vacuo with a reflective silver layer 13 and a magnetic layer 14 of Fe-Co, Fe, Co or Ni whose thickness is of the order of one ...
B1, B2--rays B1a and B2a--rays FIGS. 1-3--DESCRIPTION OF FIBER-OPTIC PROBE As shown in FIG. 1, a conventional optical fiber has a core 10 made of a material with a high index of refraction, a cladding 12 which completely surrounds core 10 and is made of a material with an index...
rays must pass through the first substance and impact upon the interface of the first and a second substance in order for the light rays to be totally internally reflected from the interface, i.e., sent back through the first substance without passing into the second substance. It should be...
(e.g., acrylate coatings). The cladding reflects light rays in the core, providing total internal reflection. The core of an optical fiber may be made of a variety of materials including glass and plastic. External surfaces of different ones of optical fibers4may be differently colored in ...
ranges of the sample constituent being detected, such as 0.01 parts per million, the pulses due to the magneto-optic rotation effect of the sample constituents may be as low as 100 per second, whereas the background noise produced by cosmic rays in the photomultiplier 18 may be on the order...
rays from an object at said object plane substantially at the entrance of said fiber optic assembly. The first light relaying means also includes a prism for dispersing the light from the object and for providing a direction of view at an angle of 30 to 60 degrees or more with respect to...
