We present an air-coupled ultrasonic imaging system based on a 40-kHz 8× 8 phased-array
for 3-D real-time localization of multiple objects in the far-field. By attaching a waveguide to …

Many popular advanced sonar systems provide accurate and reliable measurements
containing crucial info needed by robotic applications such as range, bearing and reflection …

Sonar or ultrasonic sensing uses the propagation of acoustic energy at higher frequencies
than normal hearing to extract information from the environment. This chapter presents the …

Airborne 3D imaging using ultrasound is a promising sensing modality for robotic
applications in harsh environments. Over the last decade, several high-performance …

Sensors using ultrasonic sound have proven to provide accurate 3D perception in difficult
environments where other modalities fail. Several industrial sectors need accurate and …

This article proposes an ultrasonic sensor inspired by the shape of a bat's cochlea, which is
part of one of the most sophisticated echolocation systems to be found among mammals. In …

State-of-the-art autonomous vehicles use all kinds of sensors based on light, such as a
camera or LIDAR (Laser Imaging Detection And Ranging). These sensors tend to fail when …

In this letter, we propose a visual indoor localization technique, which localizes a camera
sensor by comparing the acquired images to a reference model of location-tagged visual …

We theoretically propose and experimentally demonstrate acoustic metasurfaces that exhibit
undistorted transmission and configurable reflection, therefore serving as remarkable veil …

Ultrasonic sonar sensors are commonly used for contactless distance measurements in
application areas such as automotive and mobile robotics. They can also be exploited to …
