中文摘要：
提出了一种改进的Herriott型长光程模拟装置,该装置由平面反射镜和凹面反射镜组成,具有等效光程长和便于光路调控的优点。本文讨论了光束直径、镜面尺寸、旋转角度、和镜面反射率对光程和光路调节的影响,并利用ABCD矩阵变换方法分析了系统的稳定性。理论模拟计算了基长为0.6m的装置实现144m有效光程传输所需的参数和结果。
英文摘要：
This paper proposes a novel design of Herriott type cell, which consists of a plane reflector and two semi-circular concave mirrors. It is with the longer equivalent optical path and easily controlled. We calculate the stability of the system using the ABCD matrix transformation method, and discuss the relationship between the beam diameter, rotation angle lens size with the adjustment and effective optical path of the system. As an example, this article gives the necessary conditions and results, which can achieve 144 m effective optical by employing the improved Herriott cell of 0.6 m distance.
