Diffraction Measurments

From OLEG

Jump to: navigation, search

The optical behavior of diffraction gratings and holograms is particularly difficult to accurately quantify. The diversity of definitions (used by different groups) reported in the literature complicates matters further. The description below establishes the standard measurement approach and terminology used within OLEG's daily practice and publications.
