This thesis mainly insight to increasing the throughput of the optical laser links and to provide very accurate pointing and tracking of the laser beam especially in the feeder links to geostationary satellites.  Investigating Gaussian beam behaviour in atmosphere  Beam measurements for various laser links  Analysis of scintillation & beam wander effect using MATLAB

Place: Institute for Nanostructure and Analysis, Kassel The main objective is to develop computer controlled gonio-photometer, to determine the luminous intensity distribution of daylight inside rooms by using “active windows” based on Micro-mirror technology. responsibilities:  Selecting optimum photo-detector  Data acquisition using NI-DAQmx  Serial communication interface with single and tri axis stepper controller using LabVIEW
