  As a promising lensless imaging method for distance objects, intensity
interferometry imaging (III) had been suffering from the unreliable phase
retrieval process, hindering the development of III for decades. Recently, the
introduction of the ptychographic detection in III overcame this challenge, and
a method called ptychographic III (PIII) was proposed. We here experimentally
demonstrate that PIII can image a dynamic distance object. A reasonable image
for the moving object can be retrieved with only two speckle patterns for each
probe, and only 10 to 20 iterations are needed. Meanwhile, PIII exhibits robust
to the inaccurate information of the probe. Furthermore, PIII successfully
recovers the image through a fog obfuscating the imaging light path, under
which a conventional camera relying on lenses fails to provide a recognizable
image.
