High-speed video camera systems
We use high-speed video cameras in a stereoscopic setup to measure the three dimensional wing and body movements (kinematics) of freely flying animals in the wind tunnel. In our lab we have two different camera setups.
One system is used for filming in infra red light (IR) and consists of two Redlake PCI 500 cameras with a maximum resolution of 480x420 pixels at 250 frames per second. The cameras are equipped with Schneider lenses with a high transparency in the IR-range and IR filters removing light in the visible range.
The second system is for filming in visible light and consists of two Photron Fastcam X 1280 cameras synchronized with a NAC Hot Shot camera. All cameras have a resolution of 1280x1024 pixels at a maximum of 500 frames per second, however the cameras can be run up to 4000 frames per second at reduced resolution.
