Abstract
A method for testing a nozzle in a nozzle plate includes jetting gas through the nozzle and forming one or more light-intensity representations of a gas stream jetted from the nozzle using at least one stationary schlieren optical system. One or more images can be captured of the one or more light-intensity representations of the gas stream jetted from the nozzle. Alternatively, respective light-intensity representations of the gas stream jetted from the nozzle can be projected onto a screen.
