Title (EN) LAYER FOR INDUCING VARYING DELAYS IN ULTRASONIC SIGNALS PROPAGATING IN ULTRASONIC SENSOR
(FR) COUCHE POUR INDUIRE DIVERS RETARDS DANS DES SIGNAUX ULTRASONORES SE PROPAGEANT DANS UN CAPTEUR ULTRASONORE
Abstract:
(EN) An apparatus includes an ultrasonic transmitter, an ultrasonic receiver, and an acoustic delay gradient layer disposed in an acoustic path between the ultrasonic transmitter and the ultrasonic receiver. The acoustic delay gradient layer is configured to cause a reflection from a platen interface of the transmitted ultrasonic signal to reach the first receiver region at a first time and the reflection from the platen interface of the transmitted ultrasonic signal to reach the second receiver region at a second time that is different from the first time. The apparatus can further include a controller configured to set for a first region or portion of the receiver, a first range gate window (RGW). The controller is also configured to set, for a second region or portion of the receiver, a second RGW, and to establish a first temporal delay between the first RGW and the second RGW.
(FR) Appareil comprenant un émetteur ultrasonore, un récepteur ultrasonore et une couche de gradient de retard acoustique disposée dans un chemin acoustique entre l'émetteur ultrasonore et le récepteur ultrasonore. La couche de gradient de retard acoustique est conçue pour provoquer une réflexion à partir d'une interface de platine du signal ultrasonore transmis pour atteindre la première région de récepteur à un premier moment et la réflexion à partir de l'interface de platine du signal ultrasonore transmis pour atteindre la seconde région de récepteur à un second moment qui est différent du premier moment. L'appareil peut en outre comprendre un dispositif de commande conçu pour régler, pour une première région ou partie du récepteur, une première fenêtre de porte de distance (RGW). Le dispositif de commande est également conçu pour régler, pour une seconde région ou partie du récepteur, une seconde RGW, et pour établir un premier retard temporel entre la première RGW et la seconde RGW.
