Abstract
If you hold a video camera or binoculars to your eyes, the perceived picture will fluctuate a little. These involuntary fluctuations, called physiological tremor, are caused by the limb muscles which hold the optical device in a constant position relative to the eyes and the object looked at. The frequency of these mechanical fluctuations is in the range of 8–12 Hz for the upper limbs, and can be detected by the visual system.
