光幕性能测试系统数学建模和软件设计

Mathematical modeling and software design for screen performance measuring system

光幕性能测试系统主要是为研究更大规模的光幕靶和密集度靶提供必要的数据准备和理论基础的。研制出了用于探测光幕靶、密集度靶等光幕面内光能分布情况(光强度、一致性、均匀性)的测试仪器。光幕光能量数学模型的建立和光幕性能测试软件是非常重要的。为了了解其功能对光幕发光的情况,利用Visual C++6.0开发工具设计了一个光幕性能测试系统软件,实现了光能分布情况的采集和处理。文章从数学建模及软件设计两部分着重介绍了该系统的设计过程。测试结果表明,基本符合理论分析的光场能量计算公式,为光幕性能测试系统提供了可靠的数据和软件支持,提高了光幕性能测试系统的质量。

The Screen Performance Measuring System is mainly for studying a larger screen target and intensity of target to provide the necessary data and theoretical basis. A testing equipment for detecting screen＇ s light distribution （light intensity, consistency, uniformity） is developed, such as screen target and intensity of target. The setting of screen light energy mathe- matical model and screen performance Measuring software is an important part. In order to achieve their functions, using Visual C＋＋ 6.0 development tool, the collection and processing of the energy distribution are achieved. The system design process from the mathematical modeling and software design is introduced. The testing results show that they are consistent with theoretical analysis of the light energy formula, the quality and level of the Screen Performance Measuring System are improved.
