Application of Schlieren photography for visualisation of a pulsed gaseous target

Abstract

The article describes Schlieren photography, realised using a laser plasma as a radiationsource. Optical systems prepared for visualisation of a stationary gas outflow and a pulsed gaseoustarget, produced in an atmosphere or vacuum environment are presented. A He-Ne laser beam orlaser plasmas were used as the light sources. Schlieren images of outflows of helium, carbon dioxide,krypton, nitrogen and sulphur hexafluoride, are presented. A comparison of various gas streams,formed in atmosphere, imaged using different light sources are shown. Schlieren images of a twostreamgaseous target formed in vacuum are also presented.Keywords: automation, electronics, electrical engineering and space technology, refraction, opticalsystem, laser plasma, schlieren photography
