OPTIMUM LASER DETECTION

Abstract

The Increasing sophistication of optical cospoflsnts and techniques, coabined with rapidly Increasing corinuntcr tion requirements suggests that optical sys4ems operating within the atmosphere may represent desirable solutionto real communicationproblems. The design of such systems is strongly influenced by considerations of atmospheric turbulsnce ► The promising alternative is the heterodyne system operating at 10.60. An attempt is mode to optimise a given system for a particular sot of performance parameters and with a fixed value of total system m cast. Computational technique is used for the evaluation of the optimum system parameters with a transmission wavelength of 10.60. The need for the development of adequate modulators and the study of different modulation techniques in view of the aspheric effects is contemplated
