The cylindrical surfaces were observed with a laser microscope having a wide field of view. When the cylindrical specimens are rotated by a motor-driven rotary table, the focused laser light is scanned along a generatrix of the cylinder surface. Thus, the whole cylinder surface is easily observed even in the very short time. Since the obtained image is a developed view of the cylinder surface, it is easy to measure a distance between any two points on the cylindrical surface. As an example of the cylindrical surface, a TiN coated 4-edge end mill of 10 mm in diameter was observed. Each cutting edge appears to be a spiral on the cylindrical surface. However, we became aware of the cutting edge was a straight line when the cylindrical surface of the end mill was developed. The cylindrical surface of the end mill was very uneven. It is very difficult to focus on the cylindrical surface because of the very large distance between the high and low levels. However, this laser microscope has a deep depth-of-focus so the whole image of the end mil l can be obtained at a time without additional adjustment of focus. Several types of cylindrical surfaces were observed.

用宽视场的激光显微镜观察圆柱形表面。当圆柱形试样被电机驱动的转台旋转时，聚焦的激光沿着圆柱体表面的母线扫描。因此，即使在很短的时间内也可以很容易地观察到整个圆柱体表面。由于所得到的图像是柱面的展开视图，因此很容易测量柱面上任意两点之间的距离。以圆柱表面为例，观察了直径为10 mm的镀TiN四刃立铣刀。每个切削刃在圆柱形表面上看起来都是螺旋形的。然而，当立铣刀的圆柱形面被开发出来时，我们意识到切削刃是一条直线。立铣刀的圆柱面很不平整。由于高、低水平之间的距离非常大，因此很难对圆柱形表面进行聚焦。然而，这种激光显微镜有一个深的聚焦深度，所以整个图像的端铣1可以在一次获得，而无需额外的调整焦点。观察了几种类型的圆柱形表面。
