Planar micro-optic solar concentrator

We present a new approach to solar concentration where sunlight collected by each lens in a two-dimensional lens array is coupled into a shared, planar waveguide using localized features placed at each lens focus. This geometry yields a thin, flat profile ...

A colloidal approach to eye lens protein mixtures

Nicolas Dorsaz

A broad and constantly growing class of diseases, such as Alzheimer's disease, sickle-cell or cataract, involves protein association phenomena as an essential aspect. The common denominator of all the members of this class of molecular condensation disease ...

3-D modulable PDMS-based microlens system

Luis Guillermo Villanueva Torrijo, Victor Javier Cadarso Busto

The design, simulation, fabrication and characterization of 3-D modulable micro-optical system based on poly-dimethilsiloxane (PDMS) are presented in this paper. This system consists on two uncoupled PDMS lenses with different diameter (2 and 10 mu m). Und ...

Dynamic Perception after Visually Guided Grasping by a Human-Like Autonomous Robot

Mototaka Suzuki, Kuniaki Noda

We will explore dynamic perception following the visually guided grasping of several objects by a human-like autonomous robot. This competency serves for object categorization. Physical interaction with the hand-held object gives the neural network of the ...

Numerical aberrations compensation and polarization imaging in digital holographic microscopy

Tristan Colomb

In this thesis, we describe a method for the numerical reconstruction of the complete wavefront properties from a single digital hologram: the amplitude, the phase and the polarization state. For this purpose, we present the principle of digital holographi ...

Miniature Cameras for Ultra-Light Flying Robots

Adam Klaptocz

The Laboratory of Intelligent Systems (LIS) at the Swiss Federal Technical Institute at Lausanne (EPFL) is working on a project to create an autonomous flying robot that uses ‘vision’ (i.e. optical flow) to maneuver through small spaces such as corridors i ...

Intraocular pressure recording system

Stefan Metz, Matteo Leonardi

A new noninvasive approach for intraocular pressure (IOP) measurement allowing continuous monitoring over prolonged periods, regardless of patient's position and activities. The key element of this measurement method is a soft contact lens (1) including at ...

Optische Augenlängenmessung für klinische Anwendungen

Beate Möller

Cataract is the leading cause of blindness worldwide. The clouding of the human eye lens is called "Grauer Star" in German. In the industrialized countries this process of increased blindness is corrected by the surgical removal of the clouded lens and its ...

Compact multisensor laser scanning head for processing and monitoring microspot welding

René Salathé, Thomas Sidler, Moustapha Hafez

In order to improve the reliability of micro-spot welding of metal parts in production such as e.g. in electron guns for TV picture tubes, real-time information about the evolution of the welding process should be available to allow on-line modification of ...
