The personnel should increase the power of cell phone jammer .
In many aspects of the theory and technology of a lot of work to be overcome, to be able to reduce the error to achieve the precision angle measurement. The fiber optic gyroscope is also based on the Sagnac effect. To the length of the fiber is wound by a circle diameter of the fiber ring, its diameter can be expressed as Thus, in order to increase the optical path difference, one way is to increase the diameter, one approach is to increase the number of laps. For the fiber in terms of the latter method is easy to achieve. Practical ring laser angle measurement is the use of fiber optic gyroscopes. Figure 6-39 Examples of fiber-optic gyroscope. Figure 6-39 fiber-optic gyroscope schematic. Measurement of laser environment. Laser environment measurement [31,32] the use of laser radar. The lidar (laser in radar), also known as LIDAR (optical in radar). Laser radar detection sensitivity on the particles in the atmosphere is very high. It has been increased to the needed value and level of cell phone jammer .So that it can protect cell phone jammer well
Using the spectrophotometric method, can determine the distribution of the specific composition of the atmosphere, and thus become the most effective means of atmospheric environment measurement. If you are using a picosecond pulsed laser, the spatial resolution of less than 10 cm. Figure 6-40 Schematic diagram of the laser radar. Figure 6-40 laser radar diagram. When the light propagation encountered in the refractive index discontinuity, will be there as a new source of light waves scattering. Changes in accordance with the energy of the photon scattering into inelastic scattering and elastic scattering of two types. Elastic scattering, there are Rayleigh scattering and Mie scattering of points. Relative to the laser wavelength, the scattering body size is very small (air molecules), known as Rayleigh scattering. The power of cell phone jammer is also the important reference basis.
Fairly with the laser wavelength (suspended particulates in the air) scattering, called Mie scattering. Rayleigh scattering intensity and irradiation laser wavelength is inversely proportional to the fourth power, therefore, by changing the wavelength of measurement can be opened and the Mie scattering difference. Corresponding to inelastic scattering Raman scattering and Brillouin scattering. Is to use these scattering measurement technology, the application of lidar observations of atmospheric environment is very active. The laser beam is fired into the air to air a distance of hundreds of kilometers away suspended solids (gases, particles) initiative of the distance measurement. Through the measurement of scattered light, it can determine whether there is a disorder of airflow (Mie scattering), as well as the type and quantity of of CO, NO, N2O, SO2, H2S, and other atmospheric pollutants (Raman scattering) in the air. Different cell phone jammer of different power degrees have different laser energies.
