Influence of temperature gradient at the reflectors on the bit-error rate in periscope laser communication systems in the presence of platform vibrations

We propose a reflector back-fixing method for substantially improving the pointing accuracy in comparison with the around-fixing method. We use the developed model for analyzing the bit-error rate (BER) in the presence of the satellite’s platform vibration. We consider the relationship between the B...

Summary:We propose a reflector back-fixing method for substantially improving the pointing accuracy in comparison with the around-fixing method. We use the developed model for analyzing the bit-error rate (BER) in the presence of the satellite’s platform vibration. We consider the relationship between the BER and temperature gradient at elliptical reflectors, in view of the two fixing methods mentioned above. We also analyze the effect of beam wavelength and truncation ratio on the BER. We find that the back-fixing of the reflectors can reduce substantially the BER, thus, providing stabler performance of periscope laser-communication systems.
