The invention discloses an ultrasonic co-frequency observation device and method for directly displaying a second modal wave. The ultrasonic co-frequency observation device comprises a second modal wave detection device, an ultrasonic co-frequency optical path system and an image acquisition system, the second modal wave detection device is used for detecting a pressure signal of the second modal wave; the ultrasonic same-frequency light path system is used for providing a light source for the display of the second modal wave, emitting a light beam matched with the frequency of the pressure signal, and focusing the light beam to form an image of a point light source; and the image acquisition system is used for shooting and recording the image.
本发明公开了一种用于第二模态波直接显示的超声同频观测装置及方法,包括第二模态波检测装置、超声同频光路系统和图像获取系统;所述第二模态波检测装置用于检测第二模态波的压力信号;所述超声同频光路系统用于为第二模态波的显示提供光源,发射与所述压力信号频率相匹配的光束,并将光束聚焦形成点光源的图像;所述图像获取系统用于拍摄并记录该图像。
