Case Study

The Flying Eye: Camera makes currents visible in gliding flight

For a glider to glide as long as possible, air has to flow perfectly around the airfoils. To find out if it does, you need either a multi-million Euro wind tunnel or some 3 meter wool threads and a USB camera.

Cameras

CAM102: Bayer filter camera tutorial

Users of single chip color digital cameras have lots of choices in camera features. This whitepaper discusses some issues to consider when choosing a camera.
