摘要
便携式微型化是光谱仪器一个重要发展趋势。介绍了一种利用最新的ARM嵌入式处理器的U SB接口微型分光光度计原理及其信号处理方法。讨论了用LPC 2212驱动线阵CCD(TCD 1304AP),视频信号A/D转换,探讨U SB接口芯片FT 8U 232BM硬件设计、信号传输以及应用程序的编写等。
Portable mini-spectrometer is an important trend. Signal procession of micro-spectrophotometer with ARM microprocessor is introduced in this paper. Discuss the driver of linear CCD （TCD1304AP） with LPC2212 and A/D converting of video signal. The USB interface is introduced according the FT8U232BM chip of future technology. The design of hardware, signal transmitting and application program is also discussed.
