在描述光学渡越辐射源的基础上，利用衍射理论计算了光学渡越辐射（OTR）单粒子像的尺寸。这种方法允许分析发射屏幕和成像系统的有限尺寸的影响。实际的实验条件在处理强度尾问题的作用进行了估计。结果表明，通过利用OTR的偏振特性，可以实现空间分辨率的相当大的增强，这变得非常类似于标准点源。[S1098-4402（98）00017-2]
An evaluation of the optical transition radiation (OTR) single particle image dimension is obtained using diffraction theory based on a realistic description of the radiation source. This approach allows the analysis of the effect of the finite size of the emitting screen and of the imaging system. The role of practical experimental conditions in treating the intensity tail problem is estimated. It is shown that, by exploiting the polarization properties of OTR, a considerable enhancement in the spatial resolution can be achieved, which becomes very similar to that of a standard point source.
