WPG-30 model microprocessor controlled rotating beryllium mirror scanning camera and its applications
Abstract
This article elucidates the principal technical capabilities of the newly test manufactured WPG-30 Model microprocessor controlled rotating beryllium mirror scanning or streak camera, its special features and the status of its initial applications in experiments on the mechanics or dynamics of explosions. This camera opts for the use of beryllium mirror turbines, a scanning or streak speed (writing time) of 15km/s, and, in conjunction with this, maintains strong optical energy. Because of this, it raises its interval resolution capability. It makes use of a microprocessor controlled unit raising the camera's degree of automatic control and measurement speed precision. Through detonation experiments, it has been clearly shown that this type of new camera, both in its ability to discriminate or resolve differences in wave forms and in its ability to discriminate or resolve differences in wave forms and in its precision of measurement of time duration intervals, represents a very large increase.
