Light microscope with reconfigurable sensor array

Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic

A light microscope comprises a light source (10) for illuminating a specimen (35), a sensor array (60) comprised of photon-counting detector elements (61, 62) for measuring detection light (15) coming from the specimen (35), and a control device (70) for c ...

Rapid Analysis of Arbitrary-Shaped Conformal Beam-Scanning Arrays

Anja Skrivervik, Denys Nikolayev

Conformal antenna arrays are able to fit seamlessly on curved 3D-shaped surfaces, which are found ubiquitously on vehicles, aircraft, a human body, etc. In addition, conformal structures can overcome the scan loss limitations of conventional planar arrays. ...

Stacked patch antenna and hybrid beamforming network for 5G picocell applications

Anja Skrivervik, Danelys Rodríguez Avila

This paper addresses the design of an antenna array for a portable picocell station with omnidirectional coverage. The proposed solution includes a stacked patch antenna as a single radiating element of the antenna array and a hybrid beamforming network. T ...

Broadbeam microstrip patch antenna using higher order modes

Anja Skrivervik, Ismael Vico Triviño

The aim of this contribution is to assess the potential of using various microstrip radiating elements excited with different modes to achieve wide pattern beamwidths. The proposed antenna is made in classic microstrip technology and consists of a circular ...

Sinobeam: Focused Beamforming for PET Scanners

Paul Hurley, Matthieu Martin Jean-André Simeoni

Focused beamformers have been extensively used in phased-array signal processing, leading to simple and efficient imaging procedures, with high sensitivity and resolution. The beamshape acts as a spatial filter, scanning the intensity of the incoming signa ...

GNSS Multipath Estimation and Mitigation Using a Rotating Antenna

Pierre-André Farine, Joaquin Cabeza de Pablo, Cyril Botteron, Miguel Angel Ribot Sanfelix

We describe the experimental framework that we have developed to study the use of synthetic aperture in GNSS receivers to estimate and mitigate multipath interference. By combining the signal received by a single moving antenna during different time instan ...

Beamforming-deconvolution: A novel concept of deconvolution for ultrasound imaging

Jean-Philippe Thiran, Yves Wiaux, Adrien Georges Jean Besson

In ultrasound (US) imaging, beamforming is usually separated from the deconvolution or some other post-processing techniques. The former processes raw data to build radio-frequency (RF) images while the latter restore high-resolution images, denoted as tis ...

Blind calibration of sensors of sensor arrays

Paul Hurley, Matthieu Martin Jean-André Simeoni, Giovanni Cherubini, Sanaz Kazemi

Embodiments include methods for calibrating sensors of one or more sensor arrays. Aspects include accessing one or more beamforming matrices respectively associated to the one or more sensor arrays. Source intensity estimates are obtained for a set of poin ...
