This study describes rapid prototype construction of small and lightweight push broom Hyper Spectral Imagers (HSI). The dispersive element housings are printed by a thermoplastic 3D printer combined with S-mount optical components and commercial off-the-shelf camera heads. Four models with a mass less than 200 g are presented with a spectral range in the visible to the near-infrared part of the electromagnetic spectrum. The bandpass is in the range from 1.4 - 5 nm. Three test experiments with motorized gimbals to stabilize attitude show that the instruments are capable of push broom spectral imaging from various platforms, including airborne drone to handheld operations.
本研究描述了小型轻量化推扫式高光谱成像仪（HSI）的快速原型构建。色散元件外壳由热塑性3D打印机打印而成，结合S型安装光学元件和商用现成的摄像头。展示了四种质量小于200克的模型，其光谱范围涵盖电磁光谱的可见光到近红外部分。带通范围为1.4 - 5纳米。使用电动万向节进行的三次姿态稳定测试实验表明，这些仪器能够在包括机载无人机到手持操作等各种平台上进行推扫式光谱成像。
