Abstract In this article, a micro-spectrometer was developed based on quantum dots photodetector. The quantum dots photodetector has higher sensitivity than CCD, and its photoconduction gain has achieved 1.11E8 under 0.01 picowatt irradiation at liquid nitrogen temperature. In addition, the quantum dots micro-spectrometer is coupled to the microscopic imaging spectrometer to form a dual-model microscopic imaging spectrometer, which carries out spectral collection and comparison of biological samples. The experimental results show that the transmission spectra of rat skin obtained by the dual-model microscopic imaging spectrometer are consistent, and the comparison and verification of the two spectral measurement systems are realized.

基于量子点光电探测器的微型光谱仪的设计与应用

摘要 本文研制了一种基于量子点光电探测器的微型光谱仪。量子点光电探测器比CCD具有更高的灵敏度，在液氮温度下0.01皮瓦照射下其光电导增益达到1.11E8。此外，量子点显微光谱仪与显微成像光谱仪耦合形成双模显微成像光谱仪，对生物样品进行光谱采集和比对。实验结果表明，双模显微成像光谱仪获得的大鼠皮肤透射光谱一致，实现了两种光谱测量系统的对比验证。
