| Summary: | In this paper, we present a new scheme of thermal ghost imaging: visible ghost imaging with nonvisible light, which can overcome the disadvantages of conventional thermal imaging. For the two light beams of the thermal ghost imaging, we use the nonvisible light (i.e., infrared light) as the object beam and the visible light as the reference beam. The ghost image obtained by the nonvisible light can be directly observed. The ghost imaging with nonvisible light produces a visible and colorful ghost image, which is better than the thermal-imaging technique in color and image quality. Since the ghost imaging comes from the intensity correlations, the ghost imaging effectively overcomes the effect of the interference light. We believe that this new ghost imaging may be developed into a new night-vision technique. |
