HIGH SPEED CAMERA

A new type, ultra high speed, motion picture camera is being developed in the Optics Section of the National Research Laboratories for the purpose of assisting research in the recently important fields of high speed aerodynamics, ballistics, and other high rate phenomena. It is expected that the camera will enable pictures having good resolving power to be taken at rates as high as 200,000 per sec. This report describes the principle of the camera and also describes a small experimental model that has been made. Pictures taken at the rate of 64,000 per sec. with the model are included.
