Description
描述
This type of grating is the holographic counterpart of the classically ruled concave grating, invented by Rowland in the 19th century. The Rowland grating has straight grooves which are equally spaced along a chord of the concave surface.
这种类型的光栅是经典的被统治的凹光栅的全息对应，罗兰在*十九世纪发明的。罗兰光栅有直槽，它与凹表面的一个弦相等地隔开。
