SUMMARY:End-to-End Hybrid Refractive-Diffractive Lens Design with Differen
 tiable Ray-Wave Model
DESCRIPTION:Xinge Yang and Matheus Souza (King Abdullah University of Scie
 nce and Technology (KAUST)); Kunyi Wang (King Abdullah University of Scien
 ce and Technology (KAUST), University of British Columbia); Praneeth Chakr
 avarthula (University of North Carolina at Chapel Hill (UNC)); and Qiang F
 u and Wolfgang Heidrich (King Abdullah University of Science and Technolog
 y (KAUST))\n\nHybrid refractive-diffractive lenses combine the light effic
 iency of refractive lenses with the information encoding power of diffract
 ive optical elements (DOE), showing great potential as the next generation
  of imaging systems. However, accurately simulating such hybrid designs is
  generally difficult, and in particular, there are no existing differentia
 ble image formation models for hybrid lenses with sufficient accuracy. \n\
 nIn this work, we propose a new hybrid ray-tracing and wave-propagation (r
 ay-wave) model for accurate simulation of both optical aberrations and dif
 fractive phase modulation, where the DOE is placed between the last refrac
 tive surface and the image sensor, i.e. away from the Fourier plane that i
 s often used as a DOE position. The proposed ray-wave model is fully diffe
 rentiable, enabling gradient back-propagation for end-to-end co-design of 
 refractive-diffractive lens optimization and the image reconstruction netw
 ork. We validate the accuracy of the proposed model by comparing the simul
 ated point spread functions (PSFs) with theoretical results, as well as si
 mulation experiments that show our model to be more accurate than solution
 s implemented in commercial software packages like Zemax. We demonstrate t
 he effectiveness of the proposed model through real-world experiments and 
 show significant improvements in both aberration correction and extended d
 epth-of-field (EDoF) imaging. We believe the proposed model will motivate 
 further investigation into a wide range of applications in computational i
 maging, computational photography, and advanced optical design.\n\nRegistr
