Design of Data Acquisition System Based on DSP and Optical Fiber Bundle

This paper introduces the design of a DSP-based acquisition system with high parallelism of the beam. The system uses fiber arrays connected to spatial filters as the detection devices. A TMS320LF2407A DSP is adopted as the primary embedded processor, which connects Analog to Digital (A/D) converters via I/O ports. Simultaneously, the processor realizes the parallel processing of data storage, transmission and calculation. The design of the main processor control module, the signal processing module and its corresponding software, are discussed in detail.
