Abstract

This bachelor work is concerned about the concept and realization of ray control system to make static and dynamic patterns that react on frequency spectrum that is gained by the Fouriers transformation. This is the analysis to establish frequency components from which the analysed signal is composed of. The analysis outcome is the amplitude of individual components that enables from the measured data to respectively react and change shape and size of the patterns projected on design area. Depends on what kind of frequencies are in the analysed signal, a new pattern is being made by the laser ray that has its individual shape for the input signal. The development of computational technology accelerates the calculation a algorithms of frequency signal spectrum in a real time and this e.g. enables visualization of the signal in the frequent scope. The utilising is possible in scientific measurements and in commercial electronics as well.
