CHENG Xiao, LIU Yong, ZHANG Long, et al. Design of linear CCD high-speed and high-precision measurement system based on DSP[J]. 2008, (6): 80-82. DOI: 10.13873/j.1000-97872008.06.032.
The traditional non-contact measurement system by linear CCD is unable to satisfy modern demands on speed and precision.A new measurement method is introduced
which the DSP works as signal processor
the CPLD works as timing generator
with high-speed ADC and FIFO.The cottrol part that the CPLD works with DSP to carry the efficient and flexible data acquisition is introduced in detail.The experiments show the system is efficiently and stability.
