| Abstract: | In order to improve classification precision and in situ detection of biological cells,Leukocyte subclasses are analyzed by light scattering identification method.A multidimensional optical sensing system is designed based on the characteristics of their scattering light.It can detect forward small and large angle scatter,polarized side scatter and back scatter.After optimal design of optic system structure and each element parameters,when the resolution is 80lp/mm,the MTF value is not less than 0.18.The optical efficiency of back receiver system increases 1 time.The stray light is filtered out effectively and scattering signals with a good signal-to-noise ratio can be extracted.The optical system optimized can be used in scientific research of Leukocyte identification. |
