Among flow visualization techniques, the Focusing Schlieren system has been largely ignored by the field. It is, however, a low cost solution to solving visualization of density gradients, a system with good sensitivity to visualize convection patterns in liquids or gases such as warm air rising from a flame or heated object and ultimately it is also a powerful tool for teaching many optics related principles.
