A determination is made of the radiation emitted by a linearly
uniformly accelerated uncharged dipole transmitter. It is found that,
first of all, the radiation rate is given by the familiar Larmor
formula, but it is augmented by an amount which becomes dominant for
sufficiently high acceleration. For an accelerated dipole oscillator,
the criterion is that the center of mass motion become relativistic
within one oscillation period. The augmented formula and the
measurements which it summarizes presuppose an
expanding
inertial observation frame. A
static inertial reference frame
will not do. Secondly, it is found that the radiation measured in the
expanding inertial frame is received with 100 percent 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 directions) in their
respective causally disjoint Rindler-coordinatized sectors produces an
interference pattern in the expanding inertial frame. Like the pattern
of a Young double slit interferometer, this Rindler interferometer
pattern has a fringe spacing which is inversely proportional to the
proper separation and the proper frequency of the accelerated sources.
The interferometer, as well as the augmented Larmor formula, provide a
unifying perspective. It joins adjacent Rindler-coordinatized
neighborhoods into a single spacetime arena for scattering and
radiation from accelerated bodies.
