A Full-Wave Reference Simulator for Computing Surface Reflectance
Computing light reflection from rough surfaces is an important topic in computer graphics. Reflection models developed based on geometric optics fail to capture wave effects such as diffraction and interference, while existing models based on physical opti ...
ASSOC COMPUTING MACHINERY2023Sensing of Surface and Bulk Refractive Index Using Magnetophotonic Crystal with Hybrid Magneto-Optical Response
We propose an all-dielectric magneto-photonic crystal with a hybrid magneto-optical response that allows for the simultaneous measurements of the surface and bulk refractive index of the analyzed substance. The approach is based on two different spectral ...
2021Alertness in work environments - on the role of indoor daylight exposure
Light enables to see the world around us, while playing a key role in our biological functioning. During the last decades, light has become an important research topic for chronobiologists and neuroscientists, and their findings are increasingly interwoven ...
EPFL2021Specular Manifold Sampling for Rendering High-Frequency Caustics and Glints
Wenzel Alban Jakob, Tizian Lucien Zeltner
Scattering from specular surfaces produces complex optical effects that are frequently encountered in realistic scenes: intricate caustics due to focused reflection, multiple refraction, and high-frequency glints from specular microstructure. Yet, despite ...
ASSOC COMPUTING MACHINERY2020Multi-Channel Front-End for Electrochemical Sensing of Metabolites, Drugs, and Electrolytes
Giovanni De Micheli, Sandro Carrara, Mandresy Ivan Ny Hanitra, Francesca Criscuolo, Nadezda Pankratova
A multi-channel front-end for electrochemical sensing is presented. It consists of a multiplexed four-channel readout interface supporting amperometric, voltammetric, and potentiometric measurements. The electronic interface is co-designed according to the ...
2020On data assimilation with Monte-Carlo-calculated and statistically uncertain sensitivity coefficients
Andreas Pautz, Mathieu Hursin, Daniel Jerôme Siefman
Sensitivity coefficients from Monte Carlo neutron transport codes have uncertainties that can affect nuclear data adjustments with integral experiments. This paper presents an extended version of Generalized Linear Least Squares (GLLS), called xGLLS, that ...
PERGAMON-ELSEVIER SCIENCE LTD2020Mitsuba 2: A Retargetable Forward and Inverse Renderer
Wenzel Alban Jakob, Tizian Lucien Zeltner, Delio Aleardo Vicini, Merlin Eléazar Nimier-David
Modern rendering systems are confronted with a dauntingly large and growing set of requirements: in their pursuit of realism, physically based techniques must increasingly account for intricate properties of light, such as its spectral composition or polar ...
ASSOC COMPUTING MACHINERY2019Sampling the Multiple Facets of Light
The theme of this thesis revolves around three important manifestations of light, namely its corpuscular, wave and electromagnetic nature. Our goal is to exploit these principles to analyze, design and build imaging modalities by developing new signal proc ...
EPFL2018Single Image Reflection Suppression
Sabine Süsstrunk, Radhakrishna Achanta, Nikolaos Arvanitopoulos Darginis
Reflections are a common artifact in images taken through glass windows. Automatically removing the reflection artifacts after the picture is taken is an ill-posed problem. Attempts to solve this problem using optimization schemes therefore rely on various ...
Ieee2017Multilayer four-flux matrix model accounting for directional-diffuse light transfers
The four-flux model is a method to solve light radiative-transfer problems in planar, possibly multilayer structures. The light fluxes are modeled as two collimated and two diffuse beams propagating forward and backward perpendicularly to the layer stack. ...
