分光测色仪中的双光电路设计

分光测色仪中的光电转换器运用先进的光电传感技术(光电二极管阵列),来进行光信号的采集。其驱动脉冲由复杂可编程逻辑器件(CPLD)搭建,后端采用高精度的模/数转换器和高速的32位微处理器构成数据处理系统。同时为解决脉冲氙灯光源强度不一致的问题,采用了双光电路同步并行触发工作的结构。介绍了该系统的软硬件设计,性能评价以及应用领域。

Double-circuit design of spectral color-measurement

Photovoltaic converter of the spectral color measurement makes use of advanced sensor technology(self scanned photodiode array) to collect the optical signal.The driving pulses are built by complex programmable logic device(CPLD).A high-precision A/D converter and a 32-bit microprocessor constitute a back-end data processing system.To solve the problem that the pulsed xenon lamp has the inconsistent intensity,the instrument uses a double-circuit with synchronous parallel triggered structure.The hardware and software design,performance evaluation and application areas were introduced.
