类似于在粗糙表面上的观察，可以通过发射的光来观察到光栅上的SPS的激发。在实验装置中，见图6，1，粗糙的表面已被具有正弦表面的金属膜所取代。与粗糙表面不同，散射强度集中在一些针状的衍射峰。图6.3显示了在空气侧进入第(-1)级衍射级的光作为两个h值的入射角00的函数：h~3.3]k(上图)和h=160~(h是鼻窦轮廓的幅度)[6.4]。在左侧，再现了相关反射曲线。由于h的值不同，(A)和(B)的位置和宽度都不同。最大的激发产生最大的光发射。图6.3中没有完全调整共振情况，因为反射最小值没有达到零。
Analogous to the observation on rough surfaces, the excitation of SPs on gratings can be observed by the emitted light. In the experimental arrangement, see Fig. 6, 1, the rough surface has been replaced by a metal film with a sinusoidal surface. In contrast to rough surfaces the scattered intensity is concentrated in some needle-like diffraction maxima. Figure 6.3 demonstrates the light emission into the (-1) th diffraction order at the air side as a function o {the angle of incidence 00 for two h values: h~ 3.3] k (above) and h= 160~(h is the amplitude of the sinus profile)[6.4]. On the left the correlated reflection curve is reproduced. Both (a) and (b) differ in position and width due to the different value of h. The maximum excitation produces maximum light emission. The resonance case is not completely adjusted in Fig. 6.3, since the reflection minimum does not reach zero.
