Abstract

In the study of the atmosphere, one main task is not to influence the phenomena. This can be done by using optical methods. One of these optical methods is laser Doppler. One application that can benefit from the advantages of laser Doppler method is to determine the velocity of atmospheric flow around aircrafts. The objective of this paper is to study the influence of a laser Doppler system on the process of velocity measurements and on the measurement precision in order to optimize the system for the use in atmospheric applications. The theoretical aspects were used to simulate the phenomena and the simulations were compared with experimental determination of velocities around and aerodynamic profile using laser Doppler method. The optimization of laser Doppler systems used in atmospheric applications is necessary because if the velocity is more precisely measured than the collected environmental data can be correctly calibrated..
