摘　　要：二相线阵电荷耦合元件是将奇、偶像元信号并行输出,在数据率提高的同时却导致信号处理变得更为复杂。基于此,以TCD1703C型二相线阵电荷耦合元件为例,提出了一种通过现场可编辑门阵列产生控制时序,并利用多通道数据处理芯片进行后续信号处理的方案。试验结果表明:该方案结构简单,性能稳定,功耗低,能够达到信号处理要求,为后续应用于微型血流变分析系统奠定了基础。The parallel output signal of two-phase linear charge-coupled device(CCD) includes odd phase and even phase.Although the data rate can be improved by using this element,the signal processing becomes more complex.Therefore,taking TCD1703C as an example,a method was proposed to generate time sequence by FPGA and to process the output signal by multi-channel signal processing chips.The result of the design indicates that the system is characterized by simple framework,stable performance and low power consumption,which meets the demand of signal processing and lays a foundation for subsequent study on micro hemorheometer.
