| 摘 要： | 本文根据LiNbO3:Fe晶体在产生光致折变时折射率与入射光能之间变化呈线性关系的特点出发，做了大量在假彩色编码时密度与色调间关第的试验，找出密度、曝光时间与色调之间的定量关系。由此可以将转折片上某区域的密度换成所需要的色调。

| Abstract: | According to the characteristic linear relationship between index of refraction and emergent energy by photorefraction, a lot of tests on the relationship between density and tone in pseudocolor coding has been made. The quantitative relationship between density, exposure time and tone has been established. As a result, it is possible to transfer the density of a region in the original white-black film into a required tone. |
