Entrance slit and the grating are fixed and the exit slit scans across the Rowland circle. 入射狭缝及光栅固定起来,出射狭缝扫描过罗兰圆。
It is a Rowland circle structure based on plane waveguide and its grating facet is a plane. EDG基于平面波导的Rowland圆结构,光栅面是平面。
Analysis of two-dimensional integrated Rowland Circle grating 罗兰圆型二维集成凹面光栅的成像分析
A conventional EDG design is based on the Rowland circle on which the end points of the input and output waveguides located. 原有EDG采用Rowland圆设计,输入输出在圆弧曲线上由条形波导引出。
