Hi, the image below shows a sample non-sequential ray trace result in angle space using the detector rectangle.



 



 



May I know how are the angles in x any y defined? Is it defined as θx and θy shown in the diagram below? If not, what's the correct definition and how can they be derived from direction cosines of the ray vector (red arrow)?



Hi Boon!



The definition for angle space calculations is provided in the Help System file 'The Setup Tab > Editors Group (Setup Tab) > Non-sequential Component Editor > Non-sequential Detectors > Detector Rectangle Object.'



 





 



All the best,



Allie
