An optical mouse is a computer mouse which uses a miniature camera and digital image processing to detect movement relative to a surface. Variations of the optical mouse have largely replaced the older mechanical mouse and its need for frequent cleaning. The earliest optical mice detected movement on prepared surfaces, however they never gained ...

Schlieren photography is a process for photographing fluid flow. Invented by the German physicist August Toepler in 1864 to study supersonic motion, it is widely used in aeronautical engineering to photograph the flow of air around objects. The process works by allowing normally unobservable changes in a fluid's refractive index to be seen, [ 1 ...
