Abstract
A system for testing one or more nozzles in a nozzle plate includes a fixture for holding the nozzle plate, a gas input device for jetting gas through the nozzle, and a first stationary schlieren optical system for producing a light-intensity representation of a gas stream jetted from the nozzle. An image capture device can capture one or more images of the light-intensity representation or the light-intensity representation can be projected onto a screen.
