Method for measuring refractive index change direction and period of volume holographic grating

The invention provides a method for measuring the refractive index change direction and period of a volume holographic grating. In the first step, a diffractometer is used for measuring the structure of the volume holographic grating, and a first angle and a second angle between an incident light be...
