中文摘要：

针对爆轰时刻光谱的特点,结合多光谱测温的理论基础,采用高速率线阵CCD,设计了瞬时多光谱爆轰测温系统。通过FPGA对各个模块进行控制,完成数据的采集、存储和传输;结合多项式回归算法,拟合出爆轰瞬间光谱信息的动态波形图。在标定过程中,采用两束激光特征谱线630和532nm进行CCD的标定,确定出对应的像元序号分别是175和270。对卤钨灯的表面温度进行实时监测表明：基于高速线阵CCD的多光谱测温系统可以完成多个时刻的瞬时光谱采集;在40MHz的高速时钟驱动下,CCD的帧频可以稳定工作在73kHz。

英文摘要：

Based on the spectral characteristic of the detonation temperature,the present paper presents a measurement system of transient multi-wavelength pyrometry with the theory of multi-wavelength thermometry.The FPGA was applied as the hardware developing platform and the high-speed linear CCD was utilized.Each module was controlled by FPGA to achieve the process of real-time data acquisition,storage and transmission.Using the multiple regression analysis method,the dynamic spectral waveforms were calculated.The two laser spectral lines,630 and 532 nm,were used to calibrate the corresponding pixel sequence numbers and the No.175 and No.270 were confirmed.In this paper,the halide tungsten light was measured.The results show that the system can sample continuous spectrum signal at several different times;the CCD can stably work with 40 MHz clock and the frame scanning frequency can achieve 73 kHz.
