On the assessment of aspheric refractive microlenses
Refractive microlenses and microlens arrays are key components for many applications such as optical data communication, laser and medical devices, or cameras. In particular, refractive micro-optics enables the miniaturization of high-tech systems but also ...
EPFL2020Depth of field extension through polarization aberrations
This paper focuses on depth of field (DOF) extension through polarization aberrations. The addition of polarizing elements into an optical system allows to exploit the polarization of the incoming light as an additional degree of freedom in the optical sys ...
SPIE-INT SOC OPTICAL ENGINEERING2019Aberrations analysis of a Focused Plenoptic Camera
Toralf Scharf, Alessandro Grosso
A Focused Plenoptic Camera in Galilean configuration is studied and its aberrations behavior is interpreted with the Nodal Aberration Theory (NAT). Sequential ray tracing is applied to individual optical channels constituted by the camera objective and ind ...
2018Vibrationally and Rotationally Inelastic Scattering of Methane from Ni(111)
This thesis presents a quantum-state-resolved molecular beam study of the non-reactive scattering of methane (CH4) from a Ni(111) surface. It is one of the first experimental investigations in which the internal quantum state distribution of a polyatomic m ...
EPFL2018Evidence for eligibility traces in human learning
Michael Herzog, Wulfram Gerstner, Kerstin Preuschoff, Marco Philipp Lehmann, He Xu, Vasiliki Liakoni
Whether we prepare a coffee or navigate to a shop: in many tasks we make multiple decisions before reaching a goal. Learning such state-action sequences from sparse reward raises the problem of credit-assignment: which actions out of a long sequence should ...
arXiv2017Method and apparatus for head worn display with multiple exit pupils
Christophe Moser, Eric Tremblay
A method for displaying an image viewable by an eye, the image being projected from a portable head worn display, comprises steps of: emitting a plurality of light beams of wavelengths that differ amongst the light beams; directing the plurality of light b ...
2016Optical prism for creating multiple views of an image
Theo Lasser, Marcel Leutenegger, Stefan Geissbuehler
Optical prism comprising two external parallel and reflecting surfaces, one internal interface, parallel to said surfaces and acting as light splitter; said prism furthermore comprising an entrance side forming an angle β with respect to said interface and ...
2016Curved artificial compound-eyes for autonomous navigation
Natural compound-eyes consist of a large number of ommatidia that are arranged on curved surfaces and thus are able to detect signals from a wide field of view. We present an integrated artificial compound-eye sensor system with enhanced field of view of 1 ...
SPIE-INT SOC OPTICAL ENGINEERING2014Phase Anomalies in Micro-Optics
Hans Peter Herzig, Toralf Scharf, Myun Sik Kim
We present a comprehensive review on the latest research activities that explore the Gouy phase and indicate the recent experimental progresses for its observations in studies that rely on a longitudinal-differential interferometer. The latter is a far-fie ...
Elsevier, Amsterdam2013Microlenses with defined contour shapes
Jürgen Brugger, Victor Javier Cadarso Busto, Loïc Jacot-Descombes
Ink-jet printing of optical ink over SU-8 pillars is here proposed as a technology for obtaining microlenses with shape control. To demonstrate the flexibility of this method, microlenses with five different contour shapes (ranging from circular and ellipt ...
