提出了一种手指形状的触觉传感器，它由一个电荷耦合器件（CCD）和一个半球形光波导组成，光波导覆盖有弹性薄片并连接到一个光源。该传感器的原理基于在传感器与物体接触处产生散射光。利用CCD检测光来识别接触位置。通过对由传感器表面几何形状导出的方程进行简单计算，该传感器还能提供被触摸物体的表面法线。通过使用一个原型传感器进行实验，对传感器的基本特性进行了评估，并证实了传感器的原理。
A finger-shaped tactile sensor consisting of a charge-coupled device (CCD) and a semispherical optical waveguide covered with an elastic sheet and connected to a light source is proposed. The principle of the sensor is based on producing the scattering light at the sensor-object contact. The contact location is recognized using a CCD to detect light. By a simple calculation of the equation derived from the sensor surface geometry, the sensor can also provide the surface normal of the touched object. Through experiments using a prototype sensor, the fundamental characteristics of the sensor are evaluated and the principle of the sensor is confirmed.<<ETX>>
