200 frames/second. Uniformly white background illumination is achieved with diffuser coupled LED lamp.


Locomotion of freely walking Drosophila adults is captured with a 200 frames per second camera. A technique is being developed that allows computer-assisted, rapid tracking of the walking fly and auto-identify its legs. Spatial and temporal parameters of leg placement and coordination can be measured easily by to auto-annotating swing/stance events for each leg. No a priori labelling of legs is necessary in this technique.
