| 摘 要： | Bly Cells的红外动态景象产生器的响应速度和空间分辨率是制约其应用的两个关键因素,并由其主要部件--转换薄膜的动态特性和空间特性所确定.以Bly Cell型薄膜红外动态景象产生器转换薄膜为研究对象,根据转换薄膜的工作原理,建立了它的动态温度分布模型,计算了其在环形脉冲源作用下的不同时刻温度场及其温度变化特性,分析了转换薄膜的动态特性和空间特性.计算结果表明,导热系数和密度越小,薄膜的表面发射率越大,则其时间响应越快;导热系数、密度、发射率越小,空间分辨率越高.

| Abstract: | The response speed and spatial resolution of the Bly Cells infrared scene projector are two restrictive factors which affect the applications of the projector,and they are determined by the dynamic and spatial characteristics of the main part of the projector,the transfer membrane.The transfer membrane of the infrared scene projector based on Bly Cell was studied.The physical and mathematical models to describe the dynamic temperature distribution of the transfer membrane were established based on the its w... |
