OpticsTalks: the similarity and difference between hologram and surface relief grating

In diffractive waveguide AR design, there are two main technical routes, hologram (Bragg grating) and surface relief grating. Let us review the similarity, difference, and modelling methods for each.

Thank you all for attending. Attached is the presentation slides from the session. 

Also, below are some useful links to the examples used in the session, as well as a bonus article about OFH (Optically Fabricated Holograms)
