标题： Fabrication of a high-resolution smartphone spectrometer for education using a 3D printer

摘要： 在本文中，我们详细介绍了使用3D打印机开发用于教育的智能手机光谱仪，并通过与纸质手工光谱仪的比较对其性能进行了表征。 光学设计和构建中使用的窄缝导致在图像传感器上形成狭缝的精确图像，与纸质手工光谱仪相比具有更高的分辨率。 增加手机相机的曝光时间揭示了高分辨率下光谱的精细结构。 光谱仪内部的遮光结构在增加曝光时间时被证明能有效去除噪声。 我们期望本文提出的3D打印智能手机光谱仪可以作为教育工具，帮助学生理解光、原子、化学和物理的各个方面。 显示英文摘要

摘要： In this paper, we present the details of the development of a smartphone spectrometer for education using a 3D printer and characterized the performance by comparison with a paper craft spectrometer. The optical design and the narrow slit used in the build resulted in the formation of accurate images of the slit on the image sensor leading to a superior resolution compared to the paper craft spectrometer. Increasing the exposure time of the phone's camera revealed the fine structure of a spectrum with high resolution. The baffle structure inside the spectrometer proved to be effective in removing noise when the exposure time was increased. We expect that the 3D printed smartphone spectrometer proposed in this paper can be useful as an education tool for students to understand the various aspects of light, atoms, chemistry, and physics.
