Rambus inventors will present at the 2013 Computation Sensing and Imaging meeting. Presentations include exploring the theoretical and experimental progress in Computational Optical Sensing and Imaging research. These talks span the fundamental physics, hardware implementation, and the numerical and analytical techniques that are leading to significant improvements in imaging and sensing across various fields, such as medicine, defense, and homeland security, as well as in industrial inspection and testing. Wednesday, June 26, 2013Title: “Lensless Ultra-Miniature Imagers Using Odd-Symmetry Spiral Phase Gratings” 6:20 p.m.Patrick R. Gill, David G. Stork, Rambus Drs. Gill and Stork introduce a new type of diffractive element based on odd-symmetry phase gratings. Spiral arrangements of these gratings over photo sensors constitute a new class of unprecedentedly small computational camera. Thursday, June 27, 2013Title: “Transmissive Structured Illumination Reveals Target Depth and Cast Shadow Details Obscured by Scattering Media” 9:20 a.m.Avinash Kumar, Patrick R. Gill, Thomas Vogelsang, David G. Stork, Rambus During this presentation, Rambus engineers will describe novel methods of computing sharp shadows and depth estimates of objects immersed in highly scattering media using multi-scale structured transmissive illumination, such as modified Hadamard tiles.
