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 ...

New Inks for the Direct Drop-on-Demand Fabrication of Polymer Lenses

Jürgen Brugger, Cristina Martin Olmos, Joo Yeon Kim

The advent of cell phone cameras extensively pushed market needs for micro lenses and supported developments like the Wafer-Level-Camera Technology [1]. Different optical applications and patterning methods for micro lenses require different sets of materi ...

Validation of a Polynomial Model for Generic Cameras

This paper discusses practical implementation of a generic camera model for a wide variety of common cameras equipped with catadioptric, fish-eye, short- or long focal length lenses. A unified approach of deriving approximate model parameters followed by a ...

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 ...

Weak signals as a flexible framing space for enhanced management and decision-making

Pierre Rossel

This paper revisits theories of weak signal analysis using the concepts of 'framing' and 'meta-framing' to provide an enriched methodological environment for management and decision-making in turbulent contexts. This attempt takes place within the effort t ...

Study and fabrication of a micro scanner for optical applications

Yves Pétremand

Being currently performed on highly complex and expensive equipments, active optical alignment of single mode 10 Gb/s transmitters and receivers is proving to be the bottleneck process for high volume manufacturing. In order to alleviate this production bu ...

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 ...

Arrays of microlenses with variable focal lengths fabricated by restructuring polymer surfaces with an ink-jet device

Ramon Pericet Camara

We report of a method for fabricating two-dimensional, regular arrays of polymer microlenses with focal lengths variable between 0.2 and 4.5 mm. We first make concave microlenses by ink-jetting solvent on a polymer substrate with a commercial drop-on-deman ...

Ultrathin cameras using annular folded optics

We present a reflective multiple-fold approach to visible imaging for high-resolution, large aperture cameras of significantly reduced thickness. This approach allows for reduced bulk and weight compared with large high-quality camera systems and improved ...

A new concept for a low-cost Earth sensor: Imaging oxygen airglow with arrays of single photon detectors

Edoardo Charbon, Herbert Shea, Cristiano Niclass, Renato Krpoun, Noémy Scheidegger

This paper presents a novel concept for a compact low-cost Earth sensor based on imaging atmospheric oxygen emission at 762nm using arrays of single photon avalanche diodes (SPADs). In both nighttime and daytime there is continuous emission at 762nm due to ...
