如何使用TI的DLP+DMD组件来构建波长范围700-2500nm的土壤样品反射式扫描光栅?

Other Parts Discussed in Thread: DLPNIRSCANEVM

1、两款评估版DLP NIRscan EVM ,DLP NIRscan Nano EVM能否用于要求产生700~2500nm波长的土壤养分近红外光谱?如何改装?若不能,用TI的DLP+DMD组件,找专业公司设计光路(包括聚焦镜、光栅、探测器等等)是否可行?
2、使用那种型号的DLP和DMD组件是否可以实现测量土壤样本的漫反射光谱数据。
3、波长范围700-2500nm,分辨率1-5nm。

  • 1. 可以的.
