| Ghost imaging technology is a new imaging technology associated with the rise and fall of the optical field,the current associated imaging technology is mostly studied for its spatial information recovery.And in the imaging technology color also contains important optical information,more conducive to human eye observation has a great value of use,so in the ghost imaging technology,the recovery of the measured object color information research is very necessary.In this thesis,based on the summary of scholars for the color information recovery scheme of ghost imaging technology,the original imaging device is improved to simplify the imaging process and recover the color information of the measured object.The light source is designed according to the color superposition principle as the illumination light source in imaging;the spatial information of the measured object is reconstructed and the color information of the measured object is recovered at the same time.Simulation experiments were conducted with multiple barrel detectors and a single barrel detector,and it was found that both solutions could recover the color information of the object under test.We also edited and modified the experimental light source and changed the scale coefficients of each color component in the synthetic light source,and conducted numerical simulations to find that the quality of color images obtained by correlated imaging was independent of the coefficients of each color component in the synthetic light source in the perfect imaging state.Finally,the scaling coefficients of each color component were changed in the reconstruction process,and numerical simulations and analyses were performed.It was found that the scaling coefficients of color illumination scatter and the scaling coefficients of each color component in the reconstruction process had no effect on the final reconstruction results in the perfect imaging state.In summary,this paper designs an experimental light source for the correlation imaging process based on the color superposition principle,and recovers the color information of the measured object using only the light intensity information collected by a single barrel detector,which simplifies the experimental setup for recovering color information in the correlation imaging process compared with the existing experimental setup.According to the analysis of the numerical simulation results,it is found that the coefficients of each color component in the experimental light source and the coefficients of each color component in the second-order correlation reconstruction process,as well as the color ratio of the object under test,have no effect on the final reconstruction results. |
