摘要

为了实现高斯圆斑向平顶线斑的转化，提出了一种用于高斯光束整形的三反射镜光学系统。利用环形面对两个相互垂直方向的光线会聚、发散作用不同，标准球面具有旋转对称性质，以及二次曲面系数、非球面系数可以实现高斯分布转化为平顶分布的原理，采用ZPL语言与自动优化结合的方法完成了系统设计。设计得到了一个方向平顶的矩形光斑以及平顶线斑，整形效果良好，并结合在光学相干层析（OCT）系统中对样品照明或扫描的实际要求，通过小角度（±2°）旋转系统第一个反射镜对所得线斑进行扫描，在扫描角度内可以实现线性扫描（扫描范围约为10 mm×11 mm）。结果表明，该三反射镜系统满足轻量化、结构紧凑、不受工作波长影响的要求，是一种可行、有效的方案。

Abstract

A system of three mirrors was proposed for beam shaping. This assembly of mirrors can convert a Gaussian distribution spot into a uniform linear distributed toroidal surface with conic and high order terms. Standard surfaces were utilized to control the beam propagation direction and energy distribution. The default merit function and optical modeling were combined to incorporate operands to optimize the system's efficiency. Rectangular and line fields with uniform energy distribution in one direction were successfully demonstrated. This has direct application to illumination or scanning in optical coherence tomography. In the case of the latter

the line is linear within a specific scanning range of 10 mm×11 mm of the first mirror. It can be concluded that this system can facilitate a simpler CT setup and is effective over a wide range of wavelengths.
