An instrument for high-speed laser perfusion imaging comprises a laser source, a detector, a signal-processing unit, data memory, and a screen to display the results. A section of the sample surface is illuminated with laser light; the reemitted light from ...
In this paper, we present a novel high resolution optical imaging device on chip. It is based on a line of nano holes defined in an optically opaque aluminum film on a CMOS imaging sensor chip. Because it's free of bulky optical elements and compatible to ...
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 ...
Among advanced electronic designs, vision systems are perhaps those that have undergone the most dramatic technological revolutions of the last decades. Recently, a new family of vision systems has emerged aimed at three-dimensional (3D) imaging. Many appl ...
This paper addresses the problem of dense estimation of disparities between omnidirectional images, in a spherical framework. Omnidirectional imaging certainly represents important advantages for the representation and processing of the plenoptic function ...
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 ...

Integrated single photon avalanche detectors (SPADs) are gaining interest in applications demanding high timing resolution and high sensitivity. The recent progress of design and implementation of SPADs in CMOS technology are discussed in this paper. ...
Thick-film and LTCC (Low Temperature Cofired Ceramic) technologies are now recognised as valid platforms for the fabrication of novel devices at the mesoscale for sensor, actuator, fluidic, electrical and packaging applications. In these fields, they allow ...
Mobile communication devices now available on the market, such as so-called smartphones, are far more advanced than the first cellular phones that became very popular one decade ago. In addition to their historical purpose, namely enabling wireless vocal c ...
This work describes an image acquisition and processing system based on a new co-processor architecture designed for CMOS sensor imaging. The platform permits to configure a wide variety of acquisition modes (random region acquisition, variable image size, ...
