How do CGHs work?
CGHs are diffractive optics. The local period of the diffractive structure of a CGH helps us understand how light interacts with it:
- Thinking in terms of rays, the angle of diffraction from a CGH can be calculated using the Grating Equation.
- Thinking in terms of wavefront, CGHs can be considered Contour Maps of wavefront modification.
