A novel multichannel demodulation scheme for fiber Bragg grating temperature sensing is proposed.In this scheme,temperature sensing signals are demodulated by tracing matching FBGs,pressure and tension are imposed by computer controlled step motor to multichannel matching FBGs. After experiment data processing, the response characteristics model of the system is established. It is proved that the demodulation method has characteristics of easy mearurement,good repeatability and high accuracy.

To enhance the traditional 2D laser radar's capability acquiring geometric information of environment,a fast 3D scanning laser radar system was designed.The scanning plane of a 2D laser radar was rotated using a micro-computer controlled step motor,and the third dimension scanning was realized.After a high-speed data transmission board was developed,the real-time link between the laser radar and the data-acquiring computer was achieved.2D range measurement data and the corresponding pitching angle at different time were recorded simultaneously during the scanning process,and then a complete frame of 3D range image was formed.After analyzing the sources of the system error,the mathematical model for initial attitude error and the system eccentric error were set up,and the system was calibrated using the least square method.The experimental results show that the radar system has high data accuracy with range error less than ±30 mm within the measurement scope,and has high scanning speed up to 1.2 s/frame.

为了增强传统二维激光雷达的环境几何信息采集能力,设计了一个快速三维扫描激光雷达系统.采用了一个单片机控制的步进电机旋转二维激光雷达的扫描平面,得到第三维扫描.研制了高速数据通讯卡,实现激光雷达与数据采集计算机之间的实时传输.在整个扫描过程中,各个时刻的二维距离测量数据和相应的俯仰扫描角被同时记录下来,形成一帧完整的三维距离图像.在分析系统误差源基础上,对初始姿态误差和系统偏心误差建立了数学模型,并采用最小二乘法作了系统标定.实验结果表明,该雷达系统精度高,在量程范围内距离误差小于±30mm,扫描速度可达1.2 s/帧数据.
