本文提出了一种基于相位微分技术的新型非接触式阻抗成像仪，能够增强对组织中肿瘤存在的检测。所开发的传感器由供气系统和空气喷嘴旁边的两个基于光纤的距离传感器组成。对于周期性气压，两个距离传感器为我们提供具有各个相位的正弦输出。相位差根据两点之间组织的阻抗参数的变化而变化。该传感器的一大优点是，无论组织的颜色如何，传感器都可以工作。为了将其应用到人体肺中，使用开发的传感器在体外测量肺的阻抗参数
This paper proposes a new non-contact impedance imager based on phase differential technique enabling an enhanced detection of the existence of a tumor in tissues. The developed sensor is composed of an air supply system and two optical fiber based distance sensors next to the air nozzle. For a periodic air pressure, two distance sensors provide us with sinusoidal outputs with individual phases. The phase difference varies according to the change of impedance parameters of tissues between two points. A big advantage of the sensor is that the sensor can work irrespective of the color of tissues. Toward the implementation into human lung, the impedance parameters are measured for lung in vitro by using the developed sensor
