    What it Shows Refraction due to inhomogeneity in air is made visible by our single-mirror schlieren optics setup. The refraction can be caused by changes in the density, temperature, or pressure of the air immediately in front of the concave mirror. The schlieren imaging method 23) is known as a high-speed imaging method applicable to low refractive index media, such as air, and is also known as old-fashioned phase-contrast optical microscopy. It is one of the asymmetric imaging methods using only a half of the diffraction pattern controlled by an angle-limiting aperture.

    HOWTO: Schlieren Photography - Ian

    In Schlieren photography, this light source will be as tiny as you can make it, and so the projected image will be a thin line or a tiny dot. Now imagine that patch of air in front of the mirror. Any light passing through it will be refracted, but only a tiny amount, normally invisible.
