考虑了使用数字成像亮度计（ILMD）估计博物馆物体（绘画）垂直平面内照度分布的方法。为了从亮度分布传递到照度分布，使用反射特性接近漫反射（Lambert）的屏幕。对测量方法进行了理论和实验不确定度估计。

The method for estimating the illuminance distribution in the vertical plane of museum objects (paintings) using a digital imaging luminance meters (ILMD) is considered. In order to pass from the luminance distribution to the illuminance distribution, a screen with reflective properties close to diffuse (Lambert) reflection is used. The theoretical and experimental uncertainty estimation of the measurement method done.
