The use of glow discharge gas laser atmospheric transmission of laser communications, advanced means of communication in modern atmospheric transmission of laser communications demonstration instrument. For laser communications to transmit information is loaded in the process of laser radiation, said laser modulation, the modulated laser from the reduction of the load information in the course of said laser demodulation. As the light detector in direct response to changes in light intensity, the laser intensity modulation with modulation and more. Instruments used in current modulation is based on technology-based direct intensity modulation, the modulation signal is sinusoidal, audio, video baseband signal, modulated laser for continuous wave oscillations [14], the expression is: where I (t) as light intensity, A0, for the laser oscillation amplitude, angular frequency, Kp is the proportional coefficient, a (t) of the modulated signal. He-Ne laser modulation current of the internal mechanism is more complex, He-Ne laser by solving a small AC component of the rate equation, the discharge current under a small sinusoidal AC component of i-mode output optical power and an AC component of W's relationship. Formula shows that the W / i directly with the DC discharge current (operating point) i0, f the modulation frequency. With laser 9 internal parameters, these parameters are related. Formula and tests show that the operating point i. Determined, the current modulation is small, the modulated laser waveform and the discharge current waveform has an approximate linear relationship. Forced through the circuit to the signal modulation to the laser discharge current on the output can be modulated by the signal intensity changes in the law. Laser output light intensity modulation frequency and modulation current, the broadband signal transmission, the effect of laser modulation frequency to compensate.
This shows that changes in atmospheric conditions that affect the measurement accuracy LRCS important factor that must be corrected using a reasonable method. Dual optical detection test is the more common form of correction, to improve due to changes in atmospheric conditions to measure the impact of accuracy. Dual optical detection method to determine the time of each measurement of the atmospheric attenuation coefficient and the laser output energy, then the direction of two hemispherical reflectance with a known standard target plate compared to the calculated target analyte of LRCS, dual optical detection method has been widely the application. LRCS laser measurement system in general by the system, scattered light detection system and the corresponding measurement control and information processing system [18]. Measurement, laser targeting system to a certain frequency of a laser pulse, the target scattering, in the far field region of the scattered light detection system with the same frequency of the scattered light pulse signal acquisition and processing to extract the signal peak voltage. Based on the measurement equation and consider the impact of atmospheric laser transmission, the peak voltage of the scattered light signal type, the response rate for the detection, optical detection system for the scattering optical efficiency for the detection system of the receiving aperture area of the peak on the incident light to the target power density, as the goal of the LRCS, T is the target to the scattered light from the laser detection system, the atmospheric transmittance, R is the distance from the target to the detection system for the detection system at the peak power density of the scattered light. The customer asks the company to provide the analysis data of this kind of  Cell Phone Jammer  he wants.
