Abstract:

The operating principles and construction features of a high speed framing camera are presented. This unit was used to take up to 128 successive dynamic photographs of the structure of a metal surface using reflected light at framing rates up to 100,000 frames per second and at various fixed exposure times between 0.05 and 0.40 micro-seconds. Large field reflected light and transmitted light photographs were recorded. Examples of the different types of pictures obtained with the unit are presented and briefly discussed. Author
