Měření optické hustoty kouře

Abstract

This Bachelor thesis deals with the issue of determination of the optical density of smoke. The measurement is done in the fire chamber at the Faculty of technical safety engineering, on a photometer device 2008 COOL made by Id LAB Praha. The thesis is divided into three main parts. The first theoretical part deals with a formation of smoke, with an attenuation of light in space and with a photometer operating principle. The second part briefly describes the photometer, its individual parts and its software .The last part focuses on a measurement methodology which contains a detailed description of the preparatory work, the measurement process and the follow work.
