| Abstract: | The concept of mobile atmospheric laser communication (MALC) is introduced in this paper. Atmosphericattenuation, turbulence-induced scintillation and beam wander cause deep fades in the beam power anddegrade the optical channel. The optical transceiver presented in this paper is designed for a MALC testsystem. Currently achievable hardware performance capabilities for the MALC terminals are used as inputparameters to the analysis. A novel optical transceiver structure is designed. Link margin is analyzed usingthe MALC analysis software, our optical link analysis program. Data rate, bit-error rate, prime transmitpower requirements, optical link margin, pulse width, background signal, aperture quality and atmosphericeffects drive the optical transmitter requirements. Results are displayed as required aperture size, aperturenumber and the spacing between apertures for a given range and terminal moving speed. The aperturesize is parameterized by data rate, transmitting optical power and wavelength. Si-APD and CCD areselected as the main receive detectors. The receiver aperture, detector size (diameter), receiver speed andsensitivity are the main factors to consider in the design of the receiver. |
