Relevant Parameter Optimization of Lensless Ghost Imaging
Journal Title: 河南科技大学学报（自然科学版） - Year 2018, Vol 39, Issue 1
Abstract
In order to improve the image quality of the lensless ghost imaging, a lensless ghost imaging experimental system with second order was constructed based on the pseudo-thermal light.The effect of the correlation number, the detector size of the object arm, and the deviation of object arm and reference arm on the image quality of the lensless ghost imaging was studied.The image quality of the constructed image was evaluated quantitatively by the signal-to-noise ratio and mean square error.The results show that the image quality is no longer improved obviously when the correlation number is more than 2 000 times.To ensure the image quality of the constructed image, the detector area on the object arm is less than 1 640 μm2 and the deviation of two arms is less than 10 cm simultaneously.
