Abstract：

Traditionally,　diffusion　correlation　spectroscopy　(DCS)　calculates　blood　flow　(BF)　by　measuring　the　temporal　intensity　fluctuations　of　multiple　scattered　light　by　DCS　devices　that　fit　all　the　requirements,　which　consists　of　a　source-detector　pair,　a　data　acquisition　card,　and　a　host　computer.　In　this　paper,　a　portable　DCS　device　based　on　STM32　microcontroller　unit　(MCU)　is　proposed　in　order　to　solve　the　drawbacks　of　traditional　DCS　devices,　which　are　costly　and　bulky.　Arterial　occlusion　experiment　was　established　by　monitoring　the　subject＇s　arm　blood　flow　changes　based　on　two　devices,　simultaneously.　The　experimental　results　indicated　that　excellent　agreement　of　blood　flow　changes　measured　and　intensity　auto-correlation　function　detected　by　portable　DCS　device　and　traditional　DCS　device.　©　2023　SPIE.　All　rights　reserved.
