Hi all,
I’m trying to simulate an image formed on the sensor of a miniature camera (roughly modelled after an Arducam B0190). The problem is, the system I’m modelling is fairly large, with multiple sources, and a scattering diffuser as an essential component (i.e., there is some randomness to the ray paths), and the camera aperture is very small and relatively far from the sources. As a result, very few of the rays make it to the detector. Running about a billion rays, I end up with just a couple hundred hits on my detector, and the simulation takes over an hour.
Is there a way that I can increase the number of rays hitting the detector without increasing the number of source rays (and thereby making my simulation time even longer)?
Thanks!
