在離軸拋物面鏡（Off-Axis Parabolic mirror, OAP）光學系統中，光學品質高度仰賴各元件的準確對位與調整。然而，傳統校正方式多依賴經驗豐富之操作人員進行人工微調，不僅效率低落，亦難以達成穩定且可重現之校正結果。實務上，微調機構（如傾斜、偏移等）的微小誤差即可能引入高階像差，進而降低平行光束的波前品質。 為有效校正各微調機構對像差的影響並提升校正效率，本研究將透過波前感測器(SHWFS)驗證校正時光源的穩定情況，建立系統基準狀態。隨後針對各個微調機構進行擾動實驗，分析自由度對波前像差（以 Zernike 多項式表示）所造成之變化，進而建立一組線性擾動響應矩陣 P。該矩陣描述調機構自由度與當前量測像差間的線性映射關係，形成一套 PX=W - WOAP 之校正模型，藉以反推出最佳調整參數向量 X。本研究方法中不僅可顯著提升校正效率與準確性，亦建立一套可重複操作之標準化流程。實驗結果顯示，透過此模型校正後的波前品質有明顯改善，顯示本研究對於高階精密光學系統的調校流程具實質應用價值與推廣潛力。;In an off-axis parabolic mirror (OAP) optical system, the optical quality heavily depends on the precise alignment and adjustment of each component.However, traditional alignment methods often rely on manual fine-tuning by experienced operators, which is not only inefficient but also makes it difficult to achieve stable and repeatable results. In practice, even small errors in adjustment mechanisms (such as tilt or translation) can introduce higher-order aberrations,thereby degrading the wavefront quality of the collimated beam.To effectively compensate for the influence of adjustment mechanisms on aberrations and improve alignment efficiency, this study employs a Shack–Hartmann wavefront sensor (SHWFS) to verify the stability of the light source during calibration and establish a system baseline. Subsequently, perturbation experiments are performed on each adjustment mechanism to analyze the impact of individual degrees of freedom on wavefront aberrations, represented by Zernike polynomials. Based on these results, a linear perturbation response matrix P is constructed, describing the linear mapping between adjustment mechanism degrees of freedom and the measured aberrations. This forms a correction model expressed as P·X = W − Wₒₐₚ, which is used to determine the optimal adjustment parameter vector X. The proposed method not only significantly enhances alignment efficiency and accuracy but also establishes a standardized and repeatable calibration procedure. Experimental results demonstrate that the wavefront quality improves markedly after applying this model, highlighting its practical value and potential for implementation in the alignment of high-precision optical systems.
