Low-Latency Event-Based Visual Odometry

The agility of a robotic system is ultimately limited by the speed of its processing pipeline. The use of a Dynamic Vision Sensors (DVS), a sensor producing asynchronous events as luminance changes are perceived by its pixels, makes it possible to have a s ...

Low-latency localization by Active LED Markers tracking using a Dynamic Vision Sensor

Davide Scaramuzza

At the current state of the art, the agility of an autonomous flying robot is limited by its sensing pipeline, because the relatively high latency and low sampling frequency limit the aggressiveness of the control strategies that can be implemented. To obt ...

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 ...

Electronics for the camera of the First G-APD Cherenkov Telescope (FACT) for ground based gamma-ray astronomy

Werner Lustermann, Mathieu Ribordy, Thomas Günther Bretz

Within the FACT project, we construct a new type of camera based on Geiger-mode avalanche photodiodes (G-APDs). Compared to photomultipliers, G-APDs are more robust, need a lower operation voltage and have the potential of higher photon-detection efficienc ...

G-APDs in Cherenkov astronomy: The FACT camera

Werner Lustermann, Mathieu Ribordy, Thomas Günther Bretz

Geiger-mode avalanche photodiodes (G-APD, SiPM) are a much discussed alternative to photomultiplier tubes in Cherenkov astronomy. The First G-APD Cherenkov Telescope (FACT) collaboration builds a camera based on a hexagonal array of 1440 G-APDs and has now ...
