Abstract

The invention provides a multi-spark type high-speed photographic digital image array recording system and method, belonging to the field of a dynamic testing technology of experimental solid mechanics and a high-speed photographic image technology. The high-speed image array recording system taking a CCD (charge coupled device) array camera system as a multi-spark type high-speed photographic photosensitive plate comprises the CCD array camera system, a multi-spark type array point light source and sequential control synchronous system, a computer data processing system and the like. By adopting an optical design, light from each multi-spark type array point light source passes through a first imaging lens to lighten tested materials, and then passes through a second imaging lens to form images on the corresponding CCD array camera system. Compared with a traditional film recording system, the recording system provided by the invention can automatically acquire and process high-speed images, thus reaching the purposes of saving labor, simplifying operations and avoiding chemical pollution of processing films.

Description

technical field [0001] The invention relates to a multi-spark high-speed photography and image processing technology, which belongs to the field of experimental solid mechanics dynamic test technology and high-speed photography image technology. Background technique [0002] Multi-spark high-speed photography is an effective means to record the high-speed flow process, and it has played an important research application in the experimental dynamic fracture mechanics and the measurement of the dynamic mechanical properties of materials. However, with the development of high-speed photography technology and image processing technology, the shortcomings of traditional multi-spark high-speed photography technology have gradually emerged: expensive aerial film needs to be used to record images, and the film needs to be developed in a darkroom and produce chemical pollution. These shortcomings largely hinder the development of this technology in dynamic testing of mechanics and it...
