探讨基于线阵CCDTCD1501C实现光信号高精度测量的可行性。设计方案采用CPLD产生CCD驱动脉冲和部分系统时序,CCD输出信号经A/D转换芯片TLC5510采集后通过FIFO芯片CY7C464缓存后向上位机传送。提出了具体的系统电路设计方法和部分驱动的编程源代码。原理样机已运用于微形变测量的光纤出射条纹检测中,具有集成度高、性能稳定、精度高、成本低的优点。
Discuss the feasibility of high precision optical signal measurement based on linear array CCDTCD1501C. The design scheme uses CCD to generate CCD drive pulse and part of the system timing. The CCD output signal is transmitted to the host computer through the FIFO chip CY7C464 after being collected by the A / D conversion chip TLC5510. Proposed a specific system circuit design methods and part-driven programming source code. Principle The prototype has been used in the detection of micro-deformation of the optical fiber stripe detection, with high integration, stable performance, high precision, low cost advantages.
