Results of the visualization of the gas flow in the inner channel of an apparatus for reducing the sound of a shot using the residual chromatism of a Toepler lens device with an adjustable location of the light source are presented. Color shadow images were obtained without introduction of additional prisms, light filters, or diaphragms into the lighting part of this device. The images obtained made it possible to determine the features of the indicated flow.
