How can I change the viewing angle?

  I simulated with a fixed viewing angle(Reflectance monitor) and varied the incident angle of the light.
  But I want to simulate with different viewing angle(-90~90 degree) and I couldn't find that option in monitor object.
  So how can I get a data from a specific viewing angle?
  ex. normal incident angle, viewing angle is 30 degrees.

  What is the purpose? for reflectance, it is only along one direction. Fields to other directions are bounced back due to periodicity.
  If it is not periodic, you can integrate the far field power inside a cone. But non-periodic structures do not have fixed reflectance, as the result will change depending on source span.
