当给定加速度的固定能量预算时，我们计算出使Unruh效应最大化的轨迹，逐个模式。我们发现，对于某些加速度不均匀的轨迹，Unruh过程最有可能发生，因此可能是最好的观察。在实践中，最优轨迹的精确形式取决于加速度变化速度的实验界限。我们也证明了任意加速观测者的Unruh光谱包含完整的信息来重建观测者的轨迹。
We calculate the trajectories which maximize the Unruh effect, mode by mode, when given a fixed energy budget for acceleration. We find that Unruh processes are most likely to occur, and therefore are potentially best observable, for certain trajectories whose acceleration is not uniform. In practice, the precise form of optimal trajectories depends on experimental bounds on how fast the acceleration can be changed. We also show that the Unruh spectra of arbitrarily accelerated observers contain the complete information to reconstruct the observers’ trajectories.
