Abstract
A determination is made of the radiation emitted by a linearly uniformly ac celerated uncharged dipole transmitter. It is found that, first of all, the radiation rate is given by the familiar Larmor formula, but it is augmente d by an amount which becomes dominant for sufficiently high acceleration. F or an accelerated dipole oscillator, the criterion is that the center of ma ss motion become relativistic within one oscillation period. The augmented formula and the measurements which it summarizes presuppose an expanding in ertial observation frame. A static inertial reference frame will not do. Se condly, it is found that the radiation measured in the expanding inertial f rame is received with 100% fidelity. There is no blueshift or redshift due to the accelerative motion of the transmitter. Finally, it is found that a pair of coherently radiating oscillators accelerating (into opposite direct ions) in their respective causally disjoint Rindler-coordinatized sectors p roduces an interference pattern in the expanding inertial frame. Like the p attern of a Young double slit interferometer, this Rindler interferometer p attern has a fringe spacing which is inversely proportional to the proper s eparation and the proper frequency of the accelerated sources. The interfer ometer, as well as the augmented Larmor formula, provide a unifying perspec tive. It joins adjacent Rindler-coordinatized neighborhoods into a single s pacetime arena for scattering and radiation from accelerated bodies.
