Title (EN) SYSTEM AND METHOD FOR ULTRASONIC SENSING
(FR) SYSTÈME ET PROCÉDÉ DE DÉTECTION ULTRASONORE
Abstract:
(EN) A system and method for ultrasonic sensing, wherein an ultrasonic receiver array includes multiple ultrasonic sensor pixels, and each sensor pixel includes an ultrasonic receiver configured to read an ultrasonic signal. An ultrasonic transmitter array, composed of multiple elements, transmits ultrasonic signals which may be reflected from an object and received at the ultrasonic receivers, wherein a sensor controller applies excitation signals to the transmitter array with a temporal delay between excitation signals.
(FR) La présente invention concerne un système et un procédé de détection ultrasonore, dans lesquels un réseau de récepteurs ultrasonores comprend des pixels de capteur ultrasonore multiples, et chaque pixel de capteur comprend un récepteur ultrasonore configuré pour lire un signal ultrasonore. Un réseau d’émetteurs ultrasonores, composé d’éléments multiples, transmet des signaux ultrasonores qui peuvent être réfléchis par un objet et reçus au niveau des récepteurs ultrasonores, un dispositif de commande de capteur appliquant des signaux d’excitation au réseau d’émetteurs avec un retard temporel entre des signaux d’excitation.
