Design of a miniature laser scanning head for high-bandwidth, low-amplitude beam steering

In laser micro-manufacturing, one of the challenges is to achieve fast scanning speed for fast fabrication of complex 3D microstructures. For microstructures with nanoscale features, it is often desirable to steer laser beams from a few microns to a few te ...

Quantitative Comparison of Commercial CCD and Custom-Designed CMOS Camera for Biological Applications

Giovanni De Micheli, Sandro Carrara, René Beuchat, Yusuf Leblebici, Gözen Köklü, Julien Michel Ghaye

In biological applications and systems where even the smallest details have a meaning, CCD cameras are mostly preferred and they hold most of the market share despite their high costs. In this paper, we propose a custom-designed CMOS camera to compete with ...

FACT - The First G-APD Cherenkov Telescope (first results)

Werner Lustermann, Mathieu Ribordy, Thomas Günther Bretz

In October 2011, the first air-Cherenkov telescope utilizing Geiger-mode avalanche photodiodes commenced operations. The silicon-based devices display several advantages compared to classical photomultiplier tubes allowing for a more compact camera design ...

Omnidirectional Light Field Analysis and Reconstruction

Luigi Bagnato

Digital photography exists since 1975, when Steven Sasson attempted to build the first digital camera. Since then the concept of digital camera did not evolve much: an optical lens concentrates light rays onto a focal plane where a planar photosensitive ar ...

Automatic and Accurate Shadow Detection using Near-Infrared Information

Sabine Süsstrunk, Dominic Rüfenacht

We present a method to automatically detect shadows in a fast and accurate manner by employing the inherent sensitivity of digital camera sensors to the near-infrared (NIR) part of the spectrum. Shadows are generally found in the dark parts of an image, be ...

Light induced fluidic waveguide coupling

Christophe Moser, Eric Tremblay, Volker Günter Zagolla

We report on the development of an opto-fluidic waveguide coupling mechanism for planar solar concentration. This mechanism is self-adaptive and light-responsive to efficiently maintain waveguide coupling and concentration independent of incoming light's d ...

Single-shot, simultaneous incoherent and holographic microscopy

Christian Depeursinge, Nicolas Pavillon, Etienne Shaffer

In this work, we demonstrate single-shot, simultaneous recording and subsequent retrieval of one incoherent and two holographic (intensity and phase) images from the same camera frame. Demultiplexing of incoherent and holographic signals in the spatial fre ...

Focusing System Flexure-Mechanism for the Close-Up Imager Instrument of the ExoMars Rover

Simon Nessim Henein, Philippe Schwab

This paper presents the design of a flexure based focusing system, part of the Close-Up Imager (CLUPI) instrument which is planned to be integrated on the future ExoMars NASA-ESA Mars Rover to be launched in 2018. Various design trade-offs are discussed, i ...

Real Time Head Pose Estimation from Consumer Depth Cameras

We present a system for estimating location and orientation of a person’s head, from depth data acquired by a low quality device. Our approach is based on discriminative random regression forests: ensembles of random trees trained by splitting each node so ...

A speckle-based CMOS sensor array for arbitrary surface movement detection

Pierre-André Farine, Chao Wang, Steve Tanner

The paper presents a CMOS sensor array for the detection of speckle movements, for applications requiring accurate movement tracking of arbitrary surfaces. The array is made of eight sensors incorporating each a spatial comb filter with a pitch of 2.8μm so ...
