Bubble Localization and Rendering for the SBC

My master’s thesis was on determining methods for triangulating the position of bubbles in the superheated liquid argon bubble chambers of the Scintillating Bubble Chamber collaboration. On the surface, triangulation for these chambers seems to be a matter of doing simple 3-view triangulation. However, triangulation is complicated by the fact that the cameras for these chambers are imaging through several distortion-inducing refractive surfaces which need to be accounted for. In my report, I go over the challanges in bubble localization in more detail, propose methods for overcoming them, describe how I tested the methods by creating photo-realistic renders of the chamber using Mitsuba 3, and provide metrics on which factors most influence the resulting errors in triangulation.

This thesis was co-advised by Emma Alexander and Eric Dahl.
