We report the first (to our knowledge) experimental demonstration of lensless ghost imaging with true thermal light. Although there is no magnification, the method is suitable for all wavelengths and so may find special applications in cases where it is not possible to use lenses, such as with x rays or gamma rays. We also numerically show that some magnification may be realized away from the focal plane, but the image will always be somewhat blurred.
据我们所知，我们首次对基于真热光的无透镜鬼成像进行了实验演示。虽然没有放大功能，但该方法适用于所有波长，因此在无法使用透镜的情况下可能会有特殊应用，例如在X射线或伽马射线的应用中。我们还通过数值模拟表明，在焦平面以外可能会实现一定程度的放大，但图像总会有些模糊。
