Shock Tube Studies Using Image Orthicon Spectroscopy

Abstract
An image orthicon detection and recording system has been adapted for making spectroscopic measurements in shock tube emission studies. The system provides greater sensitivity than film and permits electronic control of both the timing and duration of the exposure. The linear response with light intensity and immediate recording of output on an oscilloscope trace makes the system a convenient diagnostic tool. A description of the system as well as quantitative spectroscopic data obtained with it is presented.
