我们讨论了使用球形障碍物作为白色光照明的成像设备。对这一现象进行了简要的描述，然后详细介绍了一种简单、紧凑的实验装置。实验结果强调了在成像装置中使用的光的空间非相干性的重要性。论证了非相干照明优于相干照明的优越性，并讨论了球形障碍物成像的一些有趣特性。
We discuss the use of a spherical obstacle as an imaging device for white light illumination. A brief description of the phenomenon is given and then a simple, compact experimental apparatus is described in detail. The experimental results underline the importance of the spatial incoherence of light used in the imaging arrangement. The superiority of incoherent over coherent illumination is demonstrated and some interesting features of imaging by a spherical obstacle are discussed.
