To solve the bottleneck of imaging speed and the issuing of precision for analogue filter and analogue demodulation of electrical capacitance tomography, this thesis puts forward and designs a digitalized system of electrical capacitance tomography. The designed system is based on the Digital Signal Processing and Field Programme Gate Array to provide a new digitalized system of electrical capacitance tomography , which includes the digital filting and the digital demodulating algorithm on the basis of the FPGA. The results of theoretics analysis and experiment show that the design has the advantages of both the high data acquisition speed and the high noise rejection ability. It can meet the needs for data acquisition system in electrical capacitance tomography very well and improve the precision of the imaging process.
