How to add power to out-coupling gratings

      Hello,

      In the waveguide based glasses development repored in most of the papapers or technical reports, there is eyepupil expansion and related out-coupling gratings onto a light guide.  And most of the output is parallel beam output. My question now is:

      How to add the power (focusing, diverging et al) on to the out-coupling surface relief gratings? which kinds of parameters can be modified for this?

      Hello,

      Is your question about Speos or Zemax ?

       

      Thanks

      Thomas
