分析胶辊与打印纸之间的接触情况对稳定送纸运行具有重要意义。为了了解接触条件，如真实接触面积和微滑移的分布，直接观察表观接触面积是必要的。然而，常规光学显微镜由于视场太窄，观察整个表观接触区域需要花费太长的时间。我们研制了一台宽视场激光显微镜，并将其应用于测量橡胶辊与玻璃板的真实接触面积的分布。胶辊发生微滑移的临界扭矩与总实际接触面积成正比。
Analysis of contact conditions between rubber rollers and printing paper is important for stable paper feeding operation. Direct observation of apparent contact area is necessary to understand contact conditions, such as distributions of real contact area and micro-slips. However, conventional optical microscopy takes too long to observe the whole apparent contact area because the field-of-view is too narrow. We developed a wide field-of-view laser microscope, and applied it to determine the distributions of real contact area of rubber rollers against glass plates. Critical torques at which micro-slips of the rubber rollers occurred were proportional to total real contact area.
