Secondly, in phase unwrapping to overcome the spread of wrong point, changing the patch of unwrapping phase is done to improve the correctness of it. then, the relation between the unwrapping phase and the height of reconstructed object is discussed detailedly. the data processing, algorithm analysis and reconstructing object are done for the collecting fringe image which are all based on matlab language, in all these achievements, the improvement and innovation aspect are following : a ) in order to stabilize the interference fringe, a new equivalent shifting object method is presented by using fringe stabilizing device to stabilize the interference fringe though moving object and ccd camera which fixed on a precise moving platform together, the experimental result shows the fringe drift is less than a / 20 in five minutes, and the equivalent phase shifting precision is x / 100
論文在全面闡述了光學三維輪廓位相測量術的發展、應用現狀、研究熱點及未來發展趨勢的基礎上，簡要介紹了傅立葉變換和相移位相輪廓測量術的基本原理，對兩種測量方法存在的問題及誤差進行詳細分析和比較；針對位相解包裹錯誤點的傳播問題，作者通過改變解包裹路徑來提高位相解包裹的正確性；分析討論從解包裹位相（ x ， y ）到再現物體的高度h （ x ， y ）物理量之間的關系，研究相應的演算法，利用matlab平臺，對實際採集的條紋圖像進行處理和輪廓重構，其中改進及創新工作主要表現在以下兩個方面： （ a ）針對干涉型結構光場干涉條紋出現的漂移抖動對相移的影響，提出了一種用條紋穩定器穩定干涉條紋，用精密移動平臺使物體和ccd攝像頭同步移動實現等效相移的方法，建立了相應的測量系統，系統的條紋穩定可以達到。 -
In order to study the thermal performance and residual stress of microelectronic subassembly, in this paper, a newly optical interferometry method for 3 - d displacement measurement is developed based on wavefront interference theory. in which the moire interferometry provide the in - plane displacement, but the system is different from the conventional interferometry, the system applies the double diffraction of the specimen grating, the in - plane displacement sensitivity is a factor of 2 higher than that of the conventional moire interferometer. twyman / green interferometry method for out - of - plane displacement measurement is adapted, the advantages of the optical set - up are structure novelty, and the fringe patterns of the displacement fields shown high contrast and spatial resolution
為了詳細研究試件的熱變形特徵以及殘余應力的影響作用，本文在波前干涉理論的基礎上，設計了一新型三維光學測試系統，該系統的平面位移測試基於雲紋干涉方法，但採用與普通雲紋干涉不同的光路系統，利用試件光柵和平面反射鏡組形成的兩次衍射，使平面位移干涉條紋倍增，測量靈敏度是普通雲紋干涉的2倍，系統的離面位移場測試採用泰曼格林干涉光路。 -
