Paper Abstract

Ultra-high speed photoelectric photographic system is one of the important methods to study the image parameters of ultrafast physical process. This paper proposes a method of combining multi-group prism optical splitter, super shutter selection image intensifier with adjustable delay and CCD picture acquisition. The proposed method solves the problem of the image cutting in the small aperture backlight illumination experiment using the pyramid-type photoelectric camera. Several ultra-high speed photographic systems are developed, which can be used for the shadow photography, and realize ultra high speed photoelectric photographic system with 43 mm-1 spatial resolution, 2x108 images/s speed, and the capability of capturing 8 images continuously (Fig. 1). In order to adapt to the strong electromagnetic interference test environment, the photographic system adopts all optical fiber communication, signal interpretation and locking, unit modularization and other technical schemes to avoid the loss of signal in the image transmission and the system mistriggering problems. The developed camera has good application to such dynamic experiments as plasma physics and the interaction between laser and substance, and satisfactory results have been achieved.
