We designed a portable Raspberry Pi-based spectrometer, which mainly consists of a white LED acting as the wide-spectrum source, a reflection grating for light dispersion, and a CMOS imaging chip aiming at spectral recording. All the optical elements and Raspberry Pi were integrated using 3-D printing structures with a size of 118 mm × 92 mm × 84 mm, and home-built software was also designed for spectral recording, calibration, analysis, and display implemented with a touch LCD. Additionally, the portable Raspberry Pi-based spectrometer was equipped with an internal battery, thus supporting on-site applications. Tested by a series of verifications and applications, the portable Raspberry Pi-based spectrometer could reach a spectral resolution of 0.065 nm per pixel within the visible band and provide spectral detection with high accuracy. Therefore, it can be used for on-site spectral testing in various fields.
我们设计了一种基于 Raspberry Pi 的便携式分光计，主要由一个充当宽谱光源的白色 LED、一个用于分光的反射光栅以及一个用于光谱记录的 CMOS 成像芯片组成。所有光学元件和 Raspberry Pi 都使用尺寸为 118mm×92mm×84mm 的 3-D 打印结构进行集成，并为光谱记录、校准、分析和显示设计了自制软件，这些功能通过触摸式液晶显示屏来实现。此外，该基于 Raspberry Pi 的便携式分光计还配备了内部电池，支持现场应用。经过一系列验证和应用测试，该基于 Raspberry Pi 的便携式分光计在可见光波段内可达到 0.065nm/像素的光谱分辨率，并能提供高精度的光谱检测。因此，它可用于各种领域的现场光谱测试。
