Multistage diffraction light produces inter - modulationlight, compression and crossover modulation for the diffraction light will directly affect the composition of the polychromatic light.
多级衍射光所引起的互调光、衍射光的压缩和交叉调制现象直接影响多色光的合成。

Remarkably, the new technique, which the researchers call absorbance modulation, makes it possible to create lines that are only about one-tenth as wide as the wavelength of light used to create them.
