Signal Processing Circuit Design Based on SOPC Technology for the Electric Field Type Time Grating Sensors

Abstract:

Signal processing circuits are proposed for the electric field type time grating sensors. The proposed design scheme integrates sampling function and processing function into a signal field programmable gate array (FPGA) based on system on programmable chip (SOPC) technology. Employing NiosII technology and adding self-defined instructions improve data processing speed for time grating sensors. The proposed signal processing circuits are simple and stabile. The proposed signal processing circuits are applied to electric field type linear time grating sensors, the experiments results that the peak-to peak measuring error is 0.3um within 200mm without any corrections.
