Abstract: | In this paper, we present a simulation method to reconstruct the object' s imaging in a ghost-imaging system. We use Laguerre-Ganssian (LG) beam as the light source which will produce the OrbitalAngular Momentum (OAM) states. In the signal arm, the object spatial information is encoded as phase,and added to the phase of the signal light. In the idler .arm, the phase of the idler light is changed according to the maximum coincidence rate in the receiver. We get each pixel matched phase of the object and reconstruct the object' s imaging in the idle arm. We demostrate some examples of the reconstruction and compare with the other reported method. The results show that our method can improve the resoltuion of the image effectively. |
