SOI digital pixel sensor based on charge pumping

Maher Kayal, Jean-Michel Sallese, Louis Harik

Abstract-In this paper, a digital pixel sensor in SOl is presented. The active part is a partially depleted Sol phototransistor. The technique elaborated in [I] was designed and implemented. Moreover, we took advantage of some of the characteristics of the ...

Absolute and high precision 3 degrees of freedom position sensor

Reymond Clavel, Florent Cosandier

We present a compact 3 degrees of freedom (dof) (X-Y-θz) absolute position sensor offering a sub-micrometric resolution. The travelling range is 15x15mm2 (translations) and ±180° (rotation), with an absolute precision better than 10μm over the whole travel ...

Steerable Features for Statistical 3D Dendrite Detection

Michaël Unser, Pascal Fua, François Fleuret, François Aguet, Germán González Serrano

Most state-of-the-art algorithms for filament detection in 3-D image-stacks rely on computing the Hessian matrix around individual pixels and labeling these pixels according to its eigenvalues. This approach, while very effective for clean data, hi which l ...

Semiconductor Image Sensing

Peter Seitz, Nicolas Blanc

Silicon is an excellent detector material for electromagnetic radiation in the wavelength range of 0.1 to 1000 nm. In the visible spectral range (400-700 nm), external quantum efficiencies approaching 100% are obtained. When combined with the amazing minia ...

High Speed CMOS Imaging: Four Years Later

Edoardo Charbon

Four years ago [1] we assessed the status of CMOS imaging for high-speed applications. We also gave an outlook of the near future in high-speed imaging In this paper we revisit the topic of high speed imaging in a slightly different angle and make the poin ...
