The appearance, apparent speed, and removal of optical effects for relativistically moving objects

ORAL

Abstract

Since various parts of an object are different distances from an observer, and light takes a finite time to reach the observer, the appearance of a relativistically moving object will be very different from that given by the Lorentz contraction. Therefore, when teaching the subject of special relativity, it is important to stress that {\it measurement} and {\it observation} are the appropriate words to use in describing length contraction -- {\bf not} ``see'' and ``appear.'' I derive equations that can be applied to a photographic image so that the Lorentz contraction can still be observed. I give equations that quantify the apparent deformation of the object and give the apparent speed of the object as a function of time. I also derive equations that can be applied to photographic images to show how a relativistically moving image will appear and apply them to photographic images.
