Pistol being fired,schlieren image. .22 calibre pistol and its bullet just after the trigger is pulled. Propellent gas can be seen in the wake of the bullet and there is a spherical shock wave centred on the end of the barrel. Convection currents are visible from the hand of the person firing. Schlieren photography provides a way of visualising density changes in transparent fluids. Light passing through a density change is refracted (bent). The imaging technique alters the brightness and colour of this refracted light to highlight these areas | |
