Abstract:

Lensless ghost imaging using sunlight could be used to take a picture of a distant object with features of 130 µm image resolution¹. Because of the unavailability of a detection system to distinguish the very wide bandwidth of sunlight, the visibility of the ghost image is very low. This article reports a study of lensless ghost imaging with sunlight to achieve 100% image visibility by taking advantage of the intensity-fluctuation correlation of sunlight.

Keywords:
