部分相幹光（partially coherent light）是指介于完全相幹光和非相幹光之間的電磁輻射形式，其波動特性在時間和空間上表現出有限的關聯性。這種光的相幹性由統計特性描述，而非單一确定的相位關系。根據Born和Wolf在《光學原理》中的定義，部分相幹光的特性可通過相幹長度和相幹時間量化，其中相幹長度指光波保持相位關系的傳播距離，相幹時間則反映相位關聯的持續時間。
從物理機制分析，部分相幹光的特性可分為兩個維度：
在實際應用中，美國光學學會（OSA）的研究表明，部分相幹光被廣泛應用于光學相幹斷層掃描（OCT）技術，通過控制相幹度可優化成像深度與分辨率平衡。國際光學工程學會（SPIE）的文獻也指出，該光源在天文學幹涉測量中能有效抑制散斑噪聲。
數學上，Goodman在《統計光學》中建立的範西特-澤尼克定理（Van Cittert–Zernike theorem）為部分相幹光的傳播特性提供了理論基礎，該定理通過互強度函數描述光場空間相幹度的演變規律。
部分相幹光（partially coherent light）是介于完全相幹光與非相幹光之間的一種光波狀态，其相幹性在時間和空間上具有有限的關聯範圍。以下是詳細解析：
核心定義
部分相幹光指光波的相位關系在一定範圍内保持穩定，但并非完全同步或完全隨機。例如，激光經過散射介質後可能變為部分相幹光，其相幹長度和相幹時間介于理想激光（完全相幹）與白熾燈光（非相幹）之間。
相幹性的維度
實際應用
部分相幹光在光學成像、全息術和激光通信等領域有重要作用。例如，在生物顯微成像中，部分相幹光可減少散斑噪聲，同時保留一定的分辨率。
對比其他類型光
如需更深入的理論分析（如相幹度數學描述），可參考波動光學相關文獻或中的物理定義。
