摘要
介绍一种自发光流场显示与测量十分有效的方法——菲涅尔透镜间接阴影方法。根据该方法组成的光学显示与测量系统具有成象清晰度高,能排除自发光的影响,并且造价低,易于操作和使用,可广泛应用于弹道学、高速碰撞、燃烧和爆轰等领域。
This paper introduces a method of optical visualization and measurement of self-luminous flow fields, which is the mehod of indirect shadowgraph with Fresnellens. The optical visualization and measurement according to this method has characteristics of high distinct photograph, can get rid of self-luminous influence, and the cost is very low, operation and use are very easy. This method and system can extensively use in Ballistics, hvpervelocity impact, burn and detonation.
