Light field moment imaging: comment.
We comment on the recent Letter [Opt. Lett.38, 2666 (2013)10.1364/OL.38.002666], in which the authors presented an imaging technique called light field moment imaging. We wish to show that this method can be associated with transport of intensity equation at the geometric optics limit.
