Zusammenfassung: | An ultrasound spatial phase modulator according to an embodiment of the present invention comprises: an ultrasound generation unit; a heating layer, which is formed at one side of the ultrasound generation unit so as to transmit ultrasound waves and can selectively radiate heat according to location; and a phase modulation layer, which is formed at one side of the heating layer so as to transmit ultrasound waves, is formed of a phase modulation material having a modulus of elasticity that varies according to temperature, and receives heat through the heating layer so as to selectively radiate heat according to location, thereby changing the wave motion of the ultrasound waves.
Un modulateur de phase spatiale ultrasonore selon un mode de réalisation de la présente invention comprend : une unité de génération d'ultrasons ; une couche chauffante, qui est formée sur un côté de l'unité de génération d'ultrasons de façon à transmettre des ondes ultrasonores et peut émettre sélectivement de la chaleur en fonction de l'emplacement ; et une couche de modulation de phase, qui est formée sur un côté de la couche chauffante de façon à transmettre des ondes ultrasonores, est formée d'un matériau de modulation de phase ayant un module d'élasticité qui varie en fonction de la température, et reçoit de la chaleur à travers la couche chauffante de façon à rayonner sélectivement de la chaleur en fonction de l'emplacement, ce qui permet de modifier le mouvement ondulatoire des ondes ultrasonores.
