On the accurate and intuitional formula, each parameter related to axial opticalintensitydistribution and focal shifts is analyzed through numerical calculation.
通过数值计算,对各个参数对光强分布和焦移的影响进行了分析。

Due Optical Transition Radiation(OTR) is produced by the hot electrons transport through solid targets, region of OTR is have lager radiation angle and opticalintensitydistribution.
The light optical spot area and the opticalintensitydistribution can be adjusted through software. The non-uniformity of response and the SNR are influenced by the noise of the detector.
