一种基于光谱技术的便携式土壤养分检测装置
摘要：
本发明提供一种基于光谱技术的便携式土壤养分检测装置，包括测量探头、平板电脑以及设置在机箱内的微处理器、光谱采集单元、驱动单元和电源，所述测量探头包括探头本体、设置在探头本体内的光源、准直透镜、光学快门、参比物质、步进电机和聚焦透镜、开设在探头本体底部且位于光源正下方的窗口以及嵌在窗口上的窗片，所述光谱采集单元包括波长范围为350nm～1000nm的第一微型光谱仪、波长范围为900nm～2000nm的第二微型光谱仪和波长范围为1700nm～2500nm的第三微型光谱仪。本发明集成度高、体积小、重量轻、成本低，便于携带，操作方便，可实现对土壤养分的原位、快速检测。
摘要（英）：

The invention provides a portable soil nutrient detection apparatus based on a spectrum technology. The detection apparatus includes a detection probe, a tablet PC, and a microprocessor, a spectrum collection unit, a driving unit and a power supply which are arranged inside a machine case. The detection probe includes: a probe body; a light source, a collimating lens, an optical shutter, a reference substance, a stepping motor and a focusing lens which are disposed in the probe body; a window, which is formed in the bottom of the probe body and is right under the light source; and a window glass sheet embedded in the window. The spectrum collection unit includes a first micro-spectrometer being 350-1000 nm in wavelength range, a second micro-spectrometer being 900-2000 nm in wavelength range, and a third micro-spectrometer being 1700-2500 nm in wavelength range. The apparatus is high in integration level, has small size and light weight, is low in cost, is portable, is convenient to operate, and can achieve in-situ and quick detection of soil nutrients.
