Rod (optics)
In cryptozoology, ufology, and outdoor photography, rods (sometimes known as "skyfish" or "solar entities") are elongated artifacts produced by cameras that inadvertently capture several of a flying insect's wingbeats. Videos of rod-shaped objects moving quickly through the air were claimed by some to be alien life forms or small UFOs, but subsequent experiments showed that these rods appear in film because of an optical illusion/collusion (especially in interlaced video recording).

Famous quotes containing the word rod:
“The tracks of moose, more or less recent, to speak literally, covered every square rod on the sides of the mountain; and these animals are probably more numerous there now than ever before, being driven into this wilderness, from all sides, by the settlements.”
—Henry David Thoreau (1817–1862)
