摘要

平行板干涉仪的实际缺陷降低了仪器的精度,影响了光谱分辨率,并可能扭曲测量的光谱线形状。不完美的镜面平行度的影响通常描述为一个单一的扩大的仪器响应函数和减少的精细值。然而,这种表征无法捕捉到色散干涉仪(如虚拟成像相控阵(VIPA))的空间场效应。为了探索这些影响,开发了一个模型来计算由非平行镜的vipa形成的条纹图案,并在距离成对成像透镜的指定距离处沿平面成像。在对已建立的VIPA模型和具有理想平行板构型的标准标准子理论进行验证之后,将新模型用于检验镜面非平行性的影响。虽然它捕获了仪器性能在光谱分辨率和精细度方面的一般损失,但它也揭示了条纹线形状失真以及整个测量领域分辨率和强度缩放的不均匀性。此外,当测量平面与透镜的后焦平面解耦时,会发生场行为的演变,并且在测量场的有限区域内恢复接近理想的仪器性能。结果与Zemax模拟和实验数据比较良好。这项工作识别和表征了由镜面平行度的实际缺陷引起的非理想光学行为,从而能够识别测量伪像,并为选择性恢复仪器精度提供补救措施。

Performance loss and recovery of virtually imaged phased arrays with imperfect mirror parallelism.

Practical defects in parallel-plate interferometers reduce instrument finesse, compromising spectral resolution, and can distort measured spectral lineshapes. The effect of imperfect mirror parallelism is usually described by a single broadened instrument response function and diminished finesse value. However, such a characterization fails to capture spatial field effects from dispersive interferometers, such as the virtually imaged phased array (VIPA). To explore these effects, a model is developed to compute fringe patterns formed by VIPAs with nonparallel mirrors and imaged along planes at specifiable distances from the paired imaging lens. Following validation against an established VIPA model and standard etalon theory with ideal parallel-plate configurations, the new model is used to examine the effects of mirror nonparallelism. While it captures the general loss of instrument performance in spectral resolution and finesse, it also reveals fringe lineshape distortions and nonuniformity of resolution and intensity scaling across the measurement field. Furthermore, when the measurement plane is decoupled from the back focal plane of the lens, there is an evolution of field behavior, and near-ideal instrument performance is recovered within a limited region of the measurement field. Results compare favorably to Zemax simulations and experimental data. This work identifies and characterizes nonideal optical behavior arising from practical defects in mirror parallelism, thereby enabling recognition of measurement artifacts, and imparts remedial measures for selective recovery of instrument finesse.
