SUMMARY:End-to-end Optimization of Fluidic Lenses
DESCRIPTION:Technical Papers\n\nMulun Na, Hector A. Jimenez Romero, Xinge 
 Yang, Jonathan Klein, Dominik L. Michels, and Wolfgang Heidrich (KAUST)\n\
 nPrototyping and small volume production of custom imaging-grade lenses is
  difficult and expensive, especially for more complex aspherical shapes. F
 luidic shaping has recently been proposed as a potential solution: It make
 s use of the atomic level smoothness of interfaces between liquids, where 
 the shape of the interface can be carefully controlled by boundary conditi
 ons, buoyancy control and other physical parameters. If one of the liquids
  is a resin, its shape can be "frozen" by curing, thus creating a solid op
 tical element. While fluidic shaping is a promising avenue, the shape spac
 e generated by this method is currently only described in the form of part
 ial differential equations, which are incompatible with existing lens desi
 gn processes. Moreover, we show that the existing PDEs are inaccurate for 
 larger curvatures. In this work, we develop a new formulation of the shape
  space lenses generated by the fluidic shaping technique. It overcomes the
  inaccuracies of previous models, and, through a differentiable implementa
 tion, can be integrated into recent end-to-end optical design pipelines ba
 sed on differentiable ray tracing. We extensively evaluate the model and t
 he design pipeline with simulations, as well as initial physical prototype
 s.\n\nRegistration Category: Full Access, Full Access Supporter\n\nLanguag
