Data processing, etc. This document applies to the measurement of the diffraction efficiency of imaging diffractive optical elements.

2 Normative references

This document has no normative references.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Main diffraction order maindiffractionorder The first diffraction order of an imaging diffractive optical element. 3.2 The ratio of the main diffraction order light energy to the total light energy at the back focal plane of an optical system containing an imaging diffraction element. 3.3 Substrate material Processing of optical materials for imaging diffractive optical elements.

4 Principle

By measuring the main diffraction order energy and the total energy of the back focal plane of the optical system containing the imaging diffraction element, and then calculating the ratio of the two, we can get The block diagram of the measurement system of the diffraction efficiency of the imaging diffractive optical element is shown in Figure 1.
