Experimental Apparatus and Results,ized light rays from the laser are expanded by a condenser lens and converted into an approximately 50 cm diameter beam of parallel light by means of the first schlieren lens or mirror. When the light beam passes through the test section, it is refracted by the density gradients associated with the gasdynamic flow field.
