标题： A small actively-controlled high-resolution spectrograph based on off-the-shelf components

摘要： 我们介绍了基于主动控制的光纤双通设计的原型内平面光栅光谱仪的设计和测试。 该系统旨在拥有尽可能少的光学表面数量的情况下做到小巧高效——目前包括准直/成像镜头、交叉色散棱镜、光栅和反射镜以将光线发送到探测器。 它由目录光学元件构建，尺寸约为20×30厘米。 它在光学波段工作，分辨率为>70,000。 光谱仪由分叉光纤馈送，一根光纤连接望远镜，另一根用于提供同时的钍氩灯光线进行波长校准。 探测器上的弧线位置实时处理，使用商业自动导星软件将弧线位置视为导星。 导星软件将所需的调整发送给机械压电致动器，这些致动器移动将光线发送到相机的镜子，消除弧线位置的漂移。 当前使用sCMOS探测器的配置提供了3.5毫像素的精度，在标准实验室环境中相当于4米/秒的速度精度。 显示英文摘要

摘要： We present the design and testing of a prototype in-plane echelle spectrograph based on an actively controlled fibre-fed double-pass design. This system aims to be small and efficient with the minimum number of optical surfaces - currently a collimator/camera lens, cross-dispersing prism, grating and a reflector to send light to the detector. It is built from catalogue optical components and has dimensions of approximately 20x30 cm. It works in the optical regime with a resolution of >70,000. The spectrograph is fed by a bifurcated fibre with one fibre to a telescope and the other used to provide simultaneous Thorium Argon light illumination for wavelength calibration. The positions of the arc lines on the detector are processed in real time and commercial auto-guiding software is used to treat the positions of the arc lines as guide stars. The guiding software sends any required adjustments to mechanical piezo-electric actuators which move the mirror sending light to the camera removing any drift in the position of the arc lines. The current configuration using an sCMOS detector provides a precision of 3.5 milli-pixels equivalent to 4 m/s in a standard laboratory environment.
