According to the theory of scalar diffraction, first, the equipollence of spatial distribution of the plane - wave interferential field and parallel projective sine grating is discussed
摘要根據標量衍射理論，首先討論了兩平面波干涉場的空間分佈與平行投影正弦光柵的等價性。 -
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。 -
Plane diffraction grating, logarithmic amplifier and stable constant - current source are used in the system, thus the performance of the instrument is enhanced significantly and the cost is reduced
