Range image palys an important role for three-dimensional object recognition. In many industrial, material, biological and social systems some properties of 3 dimensional objects are measured using a sensor. Among these properties are position and shape which play an important role in manipulation, perception, observation, inspection and monitoring of the information related to the 3 dimensional object. Various methodologies have been developed for the retrieving of 3 dimensional information.They are roughly divided into 3 categories as follows :1) To measure the distance to the object for path-planning and navigation.2) To measure the position and shape of the object for manipulation, design and inspection.3) To measure the shape of micro-structure for observation of material characteristics.The methodology of 3D imaging is figured by the distance to be measured and the resolution. The most direct rangefinder is based on the measurement of transit time or time-of-flight by detecting the phase difference between transmitted signal and received signal. This type of rangefinder has great advantages in that there are no invisible region within the image and resolution is independent of distance, in principle.This project is to develop the key technology to measure the phase difference between transmitted light and received light basen on the high speed IC-differential amplifiers and to track the position of moving objects.

距离图像在三维目标识别中起着重要作用。在许多工业、材料、生物和社会系统中，使用传感器测量三维物体的某些特性。在这些属性中，位置和形状在操纵、感知、观察、检查和监控与三维对象相关的信息方面起着重要作用。为了获取三维信息，人们已经开发了各种方法。它们大致分为三类：1)测量到物体的距离，用于路径规划和导航；2)测量物体的位置和形状，用于操纵、设计和检查；3)测量微结构的形状，用于观察材料的特性。三维成像的方法是由被测量的距离和分辨率来表示的。最直接的测距方法是通过检测发射信号和接收信号之间的相位差来测量传输时间或飞行时间。这种类型的测距仪具有图像内没有不可见区域，分辨率原则上与距离无关的优点。本项目旨在开发基于高速集成电路差分放大器的发射光和接收光之间的相位差测量和运动目标位置跟踪的关键技术。
