Supplemental Material : Details of Simulation Title Krill-eye : Superposition Compound Eye for Wide-Angle Imaging via GRIN Lenses author Shinsaku Hiura 1 , Ankit Mohan and Ramesh Raskar, MIT Media Lab Paper ID AW-19-009 This document describes the details of our simulation. We simulate the necessary optical phenomena that affect the image quality. We also show the results with an angle limiter. 1 Simulated Optical Phenomena 1.1 Misalignment Error Figure 1: Misalignment error caused by the curvature of the image surface. Since the distance from the GRIN lens to the image point B is longer than the radius of the image surface, angle S 2 (= S 1 ) is smaller than S 3 . The error rapidly converges to zero according to the decreasing S 3 as shown in Fgiure 5(a) in the paper. 1 now at Osaka University 1
