Abstract :
To improve the spatial resolution beyond the Rayleigh diffraction limit, the ghost imaging experiment with entangled multiphoton is performed. A correlation measurement system is designed for the experiment. The FPGA TDC is used to decrease the accidental coincidence counting rate. The high precision stepping motor which is automatic controlled improve the spatial resolution and simplify the experimental process.
