Defense technology and physics teaching
To) replace the splitter, starting from the role of photosynthetic light. The two fiber end face (polished) from the mirror effect. ● a child will be one output fiber II. One hundred and eleven II Ⅳ wrapped around a cylindrical piezoelectric ceramic, piezoelectric ceramics (radial) expansion can change the length of fiber (also changes the optical path), instead of moving the plane mirror. Two Michelson interferometer works as finished base. 3 dB coupler is actually run by burning or melting of two optical fibers by a part of the very rope, when a fiber light input, excitation in the other fiber in the vibration, which is called the optical tunnel effect is the electromagnetic transition. Matter waves such as the effect of fluctuations in total. If in the production process control, which would enable the two output coupler optical fiber 50% each, the VCR or radio power output (audio signal) then the input of piezoelectric ceramic (not drawn out), electrical signals into mechanical vibrations of piezoelectric ceramics, dry is to change the length of optical fiber, optical path to as mechanical vibration, also with the audio signal changes,[link widoczny dla zalogowanych], light to carry signals, and receives from the optoelectronic detector The two optical fiber end face reflected back together by the coupler after the optical signal that the interference signal. Photoelectric detector for intensity reflects the output so it is in front of the audio recorders or radio signals. The detector's output signal directly amplified drive speakers, so to complete the sound through the optical fiber from one end to another end of the transfer. These are the basic principles of optical fiber communication. Physics is the basic disciplines,[link widoczny dla zalogowanych], take the lead in discipline. We fully share the assessment of general physics at the university stage is the most basic training course, ... it is not only for the successor program to lay a broad and solid foundation in students to work after graduation,[link widoczny dla zalogowanych], it will play a huge role in itself. [21 used to be so now and in the future,[link widoczny dla zalogowanych], more so the more developed technology, which in itself shows that the modernization of both the general physics must be also possible. How much can these two examples illustrate this point. So to keep up with the times, do a good job this course of modernization,[link widoczny dla zalogowanych], is really one of General Physics of the glorious mission,
