CMOS Demodulation Image Sensor for Nanosecond Optical Waveform Analysis

Maher Kayal, Nicolas Blanc, Lysandre-Edouard Bonjour

An image sensor with 256 x 256 pixels and a pitch of 6.3 mu m, suitable for resolving ultrashort optical phenomena, is developed. It is based on a standard CMOS process with pinned photodiode option. The pixel comprises three transfer gates to allow versat ...

Design constraints on Cherenkov telescopes with Davies-Cotton reflectors

Mathieu Ribordy, Thomas Günther Bretz

This paper discusses the construction of high-performance ground-based gamma-ray Cherenkov telescopes with a Davies-Cotton reflector. For the design of such telescopes, usually physics constrains the field-of-view, while the photo-sensor size is defined by ...

Analysis of local deformation effects in resistive strain sensing of a submicron-thickness AFM cantilever

Georg Fantner, Jonathan David Adams, Maja Dukic Pjanic

Incorporating resistive strain-sensing elements into MEMS devices is a long-standing approach for electronic detection of the device deformation. As the need for more sensitivity trends the device dimensions downwards, the size of the strain-sensor may bec ...

Method to compensate the effect of the rolling shutter effect

Pierre Vandergheynst, Emmanuel D'Angelo

A method to create a video sequence of a plurality of resultant images is disclosed. The video sequence is produced from images originating from a rolling shutter acquisition sensor. ...

Super-resolution from unregistered aliased images with unknown scalings and shifts

Martin Vetterli, Feng Yang

We consider the problem of super-resolution from unregistered aliased images with unknown spatial scaling factors and shifts. Due to the limitation of pixel size in the image sensor, the sampling rate for each image is lower than the Nyquist rate of the sc ...

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 ...

A Time-Resolved, Low-Noise Single-Photon Image Sensor Fabricated in Deep-Submicron CMOS Technology

Edoardo Charbon, John Richard Walker, Marek Gersbach, Matthew Fishburn

We report on the design and characterization of a novel time-resolved image sensor fabricated in a 130 nm CMOS process. Each pixel within the 32x32 pixel array contains a low-noise single-photon detector and a high-precision time-to-digital converter (TDC) ...

Design and Implementation of Multi-camera Systems Distributed over a Spherical Geometry

Alexandre Schmid, Yusuf Leblebici, Hossein Afshari, Kerem Seyid

The current trend in constructing high-end computing systems consists of parallelizing large numbers of processors. A similar trend is observed in digital imaging where multiple camera inputs are utilized to obtain multiple images of a scene and thus enhan ...

Experimental Analysis of Lag Sources in Pinned Photodiodes

Maher Kayal, Nicolas Blanc, Lysandre-Edouard Bonjour

A measurement method is reported to distinguish the different mechanisms that lead to image lag in image sensors based on pinned photodiodes (PPDs). This new method can differentiate between the lag caused by a potential barrier or pocket and gate traps in ...
