Marine soil in-situ testing device and method
The invention provides a marine soil in-situ testing device and method.The device comprises a probe rod, a Raman spectrometer unit, a resistance confocal unit, a laser emitting system and a first spectroscope, laser is divided into two light paths through the first spectroscope, one light path enters a second spectroscope of the resistance confocal unit, and the other light path enters a third spectroscope of the resistance confocal unit; one light path enters a dichroscope of a Raman spectrometer unit, a light path entering a second spectroscope is divided into two paths which respectively enter two light dependent resistors, and when current at the two light dependent resistors is observed to be the same, focusing of the Raman spectrometer is completed, laser is focused on a micro area on the surface of a sample, and micro-area Raman spectrum detection of an object to be detected is realized; the other side of the light is subjected to Raman scattering, the wavelength of the light is changed, the light passes through the dichroscope and then is reflected by the total reflection mirror to enter the Raman spectrometer, and the soil can be further analyzed in the Raman spectrometer.
本发明提供了一种海洋土壤原位测试装置及方法，该装置包括探杆、拉曼光谱仪单元、电阻共焦单元、激光发射系统和第一分光镜，激光经过第一分光镜分为两条光路，一条进入电阻共焦单元的第二分光镜，一条进入拉曼光谱仪单元的二向色镜，进入第二分光镜的光路分为两路，分别进入两个光敏电阻，当观察到两光敏电阻处电流相同时，完成拉曼光谱仪的对焦，将激光聚焦在样品表面的微小区域，实现了待测物微区拉曼光谱检测；另一边经拉曼散射后波长发生改变的光经过二向色镜后，再经过全反射镜反射进入拉曼光谱仪，可以在拉曼光谱仪中对土壤进一步分析。
