摘　　要：介绍一种基于小波变换的测量海藻中叶绿素 a/ b的全光纤荧光光谱在线测量系统。根据小波变换具有将频率按大小分解的特性 ,本系统将其与荧光法、光纤技术相结合用于含叶绿素 a/ b的藻类荧光光谱的测量、平滑和重叠荧光峰的解析。该系统具有小型化、结构简单、探头无源、所得光谱变形小、多参数同时测量等特点。实验证明 。A on-line all optical-fiber fluorescence spectrum measuring system which can simultaneously measure Chlorophyll-a and b fluorescence spectrum in alga is introduced. Since wavelet transform can decompose signals into localized contributions of different frequency, it is applied to the technology of optical fiber and fluorescence methods to measure and to smooth the fluorescence spectrum of alga contained Chlorophyll-a and Chlorophyll-b. On this condition, the overlapping fluorescent peaks was resolved. It has the advantages of minitype,simple structure,passive sensing head, little spectral deformation, simultaneous multi-parameter measurement. It has been testified that this method is practicable.
