COMPRESSED ULTRAFAST IMAGING VELOCITY INTERFEROMETER SYSTEM FOR ANY REFLECTOR

摘要

The present disclosure provides a compressed ultrafast imaging velocity interferometer system for any reflector, comprising a light source and target system, an etalon interference system, a compressed ultrafast imaging system, a timing control system and a data processing system. An imaging device in the traditional imaging velocity interferometer system for any reflector is replaced by a compressed ultrafast imaging system, a compressed ultrafast Photography (CUP) is introduced in an imaging process, multi-frame images, i.e. three-dimensional images for two-dimensional space and one-dimensional time, are reconstructed via a single measurement by a CUP-VISAR two-dimensional ultrafast dynamic image imaging, a complete dynamic process of a two-dimensional interference fringes image is restored, and spatiotemporal evolution information of a shock wave is effectively acquired, improving an imaging performance of the imaging velocity interferometer system for any reflector in dimension, and achieving a goal that could not be achieved before.
