We describe the characterization and laboratory study of a new optical device, a circle-to-line interferometer optical (CLIO) system, for a Fabry-Perot interferometer. The CLIO system converts a circular Fabry-Perot interferometer fringe pattern into a linear fringe pattern that can be analyzed by a linear array detector or a charge-coupled device. One can achieve the circle-to-line conversion by the use of a mirrored kaleidoscope and a 90-deg segment of a 45-deg half-angle internally reflecting cone. Our laboratory results are in good agreement with theoretical predictions. The aberrations associated with this optical system are minor for large F-number optical systems, especially for the cone segment. The finesse degradation caused by this CLIO system is relatively small, which agrees with the results of a ray-trace study.
我们描述了一种用于法布里 - 珀罗干涉仪的新型光学器件——圆到线干涉仪光学（CLIO）系统的特性及实验室研究。CLIO系统将圆形法布里 - 珀罗干涉仪条纹图案转换为可由线性阵列探测器或电荷耦合器件分析的线性条纹图案。通过使用镜面万花筒和45度半角内反射圆锥的90度扇形段可实现圆到线的转换。我们的实验室结果与理论预测高度吻合。对于大F数光学系统，尤其是圆锥扇形段，与该光学系统相关的像差较小。由该CLIO系统导致的精细度下降相对较小，这与光线追迹研究的结果相符。
