Paper Abstract

Schlieren photography normally uses a background light source grid or mirror system to send light through a sample area and a second grid or a knife edge at the camera to block nondeflected light. We describe a new technique that uses the inactive areas between CCD or CMOS sensor pixels as the second grid, so only a background grid is needed. This simplifies the setup and lowers the cost of the system.
