What are Optical 카지노 슬롯 머신 규칙s?
Optical 카지노 슬롯 머신 규칙s are hair-thin strands of glass or plastic that transmit light over distances just like wires carry electricity. They're used extensively in telecommunications, datacomm, laser beam delivery, sensing, medical applications, and more.
카지노 슬롯 머신 규칙 optics have had a huge impact on modern life. In fact, the words you’re reading right now were almost certainly transmitted through 카지노 슬롯 머신 규칙 optics during at least some of their journey from a web server to your device.
Beyond telecommunications, 카지노 슬롯 머신 규칙 optics are also used in many other ways, including laser beam delivery in surgical systems and high-power industrial laser systems. They are also components in navigational systems and sensing systems for buildings, bridges, and power plants. There are numerous other specialized uses, too.
Operating principles
A 카지노 슬롯 머신 규칙 optic cable functions in very much the same way as a water pipe. Light goes in one end and comes out the other. And, just like a water pipe, the path the 카지노 슬롯 머신 규칙 takes can be long – literally several kilometers – and can go through bends and curves. This property provides tremendous flexibility (literally!) in terms of the way 카지노 슬롯 머신 규칙s can be implemented in a system. Together with the ability to transmit light over even long distances with very low loss, this accounts for the widespread utilization and commercial success of 카지노 슬롯 머신 규칙 optics.
The underlying operating mechanism of an optical 카지노 슬롯 머신 규칙 is actually quite simple. The most basic optical 카지노 슬롯 머신 규칙 consists of a circular cross-section core surrounded by a second material, called the cladding, having a lower index of refraction.
Light introduced into one end of the 카지노 슬롯 머신 규칙 at the proper angle will travel through the core and stay contained within it until it emerges out the other end. This happens because of total internal reflection. This occurs when light traveling in a material encounters an interface to a second medium with a lower index of refraction. If the light hits the interface at a low enough angle it is completely reflected – none of the light escapes. Anyone who has looked up at the surface when underwater experiences the same phenomenon. You can see directly above you, but as you try look at the surface at angles far enough from straight up, you can’t see out.
While conceptually simple, real-world 카지노 슬롯 머신 규칙s are actually quite sophisticated, both in terms of their design and fabrication. This is necessary to meet the various performance and cost targets for specific applications.
카지노 슬롯 머신 규칙 types
카지노 슬롯 머신 규칙 optics can be classified by the markets they service, as well as by various performance or construction characteristics. The simplest grouping is by application; and that typically breaks down into telecommunications/datacomm and then everything else. That latter group is often referred to as “specialty 카지노 슬롯 머신 규칙s.”
In terms of design and functionality, there are several different basic types of 카지노 슬롯 머신 규칙s, and countless design variations within those types, which are described below. Often, a 카지노 슬롯 머신 규칙 may belong to several of these groups. For example, a single-mode 카지노 슬롯 머신 규칙 may be polarization maintaining, and also ultrafast.

Ch카지노 슬롯 머신 규칙acteristics and Use |
Single-mode |
Single-mode 카지노 슬롯 머신 규칙s have a core diameter that is so small that only the lowest (and physically smallest) transverse mode can propagate. This impacts performance in several ways. For telecommunications applications, it reduces 카지노 슬롯 머신 규칙 attenuation and dispersion. This is why single-mode 카지노 슬롯 머신 규칙 is the most widely used type for long-haul telecommunications. The output of a single-mode 카지노 슬롯 머신 규칙 can be focused to the smallest possible spot size. This makes them useful for many scientific and industrial laser applications, particularly in the construction of 카지노 슬롯 머신 규칙 lasers. |
Multi-mode |
These have core diameters large enough to permit higher-order transverse modes to travel through the 카지노 슬롯 머신 규칙. This typically enables them to transmit more optical power, but they also suffer from higher dispersion. They’re also typically less costly to manufacture than single-mode 카지노 슬롯 머신 규칙s. Together, these characteristics make them popular for short-haul datacomm applications. They’re also widely used for beam delivery with higher-power lasers in materials processing, surgical, and spectroscopic applications. |
Pol카지노 슬롯 머신 규칙ization maintaining |
Normally, birefringence within an optical 카지노 슬롯 머신 규칙 scrambles the input polarization as it travels down the cable. Polarization maintaining 카지노 슬롯 머신 규칙 is intended for applications where this isn’t desirable. This includes some high-end networking applications, laser amplifiers, IFOGs, and many sensing systems. Polarization maintaining 카지노 슬롯 머신 규칙s aren’t designed to eliminate birefringence. Instead, they are single-mode 카지노 슬롯 머신 규칙s constructed to maximize it in a very specific way. The result is that power doesn’t couple from one polarization state to the other as it propagates; this maintains the input state of polarization. |
Sensing 카지노 슬롯 머신 규칙s |
Sensing 카지노 슬롯 머신 규칙s is really a category based more on application than design, although these most frequently use a pure silica core construction. It’s also common for sensing 카지노 슬롯 머신 규칙s to utilize materials and designs which deliver a high degree of thermal, chemical, and hydrogen resistance. Most 카지노 슬롯 머신 규칙 sensors for temperature, pressure, flow, acoustics, and strain are based on signals derived from Brillouin or Rayleigh scattering along the length of the 카지노 슬롯 머신 규칙, or from 카지노 슬롯 머신 규칙 Bragg Gratings (FBGs) embedded at specific locations. |
Laser and amplifier |
These are “active 카지노 슬롯 머신 규칙s” that form the basis of 카지노 슬롯 머신 규칙 lasers and several other types of light amplifiers. They incorporate a dopant to produce laser action (light amplification) along the 카지노 슬롯 머신 규칙 length. Usually, pump light is coupled into the cladding, and this energy is used to amplify seed light introduced into the 카지노 슬롯 머신 규칙 end. It’s common for them to be produced with an accompanying passive beam delivery 카지노 슬롯 머신 규칙 which is specially matched to the active 카지노 슬롯 머신 규칙. The passive 카지노 슬롯 머신 규칙 maintains the optical characteristics of the light from the active 카지노 슬롯 머신 규칙 and provides the highest possible transmission and power handling capabilities – often well into the multi-kW level. |
Ultrafast |
This includes both active and passive 카지노 슬롯 머신 규칙s specifically designed for use with short pulsewidths and high peak powers. Applications include ultrafast 카지노 슬롯 머신 규칙 lasers, chirped pulse amplification, narrow linewidth amplifiers, and frequency doubling. There are many different design forms for ultrafast 카지노 슬롯 머신 규칙s depending upon the specific use. But they all commonly require tight polarization and dispersion control, high beam quality, and low photodarkening. |
How are 카지노 슬롯 머신 규칙 optics made?
A single 카지노 슬롯 머신 규칙 optic cable that might be kilometers long starts out as a glass tube of only a meter or two in length. A chemical process is used to transform the material on the inside diameter of the tube and increase its refractive index. Then, the tube is collapsed down into a solid cylinder, and piece from the center of this rod is cut out to make what is called a preform.
The preform is placed into a drawing tower. It’s heated until it softens and then end is pulled to form a thin strand. The strand is continuously wound over pullies to produce the cable. A polymer coating is applied to the outside of the 카지노 슬롯 머신 규칙 during this process. This will make the finished 카지노 슬롯 머신 규칙 more robust and easier to handle.
Some optical 카지노 슬롯 머신 규칙s are not circularly symmetric. An example of this would be “panda” type polarization maintaining 카지노 슬롯 머신 규칙s. A more complex series of steps are used to build the preforms for these types of 카지노 슬롯 머신 규칙s.
