Title (EN) BIASING OF CAPACITIVE MICROMACHINED ULTRASONIC TRANSDUCERS (CMUTS) AND RELATED APPARATUS AND METHODS
(FR) POLARISATION DE TRANSDUCTEURS ULTRASONORES MICRO-USINÉS CAPACITIFS (CMUT) ET APPAREIL ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) Electrical biasing of ultrasonic transducers of an ultrasound device is described. The ultrasonic transducers may be capacitive micromachined ultrasonic transducers (CMUTs). The ultrasonic transducers may be grouped together, with the different groups receiving different bias voltages. The bias voltages for the various groups of ultrasonic transducers may be selected to account for differences between the groups.
(FR) L'invention concerne la polarisation électrique de transducteurs ultrasonores d'un dispositif à ultrasons. Les transducteurs ultrasonores peuvent être des transducteurs ultrasonores micro-usinés capacitifs (CMUT). Les transducteurs ultrasonores peuvent être regroupés, les différents groupes recevant différentes tensions de polarisation. Les tensions de polarisation des différents groupes de transducteurs ultrasonores peuvent être sélectionnées pour représenter les différences entre les groupes.
