Compensating algorithm of phase - shifting error and its application in digital microscopy holography 余弦拟合消除相移误差在显微数字全息术中的应用
Digital holography is a new holographic imaging technique and has been applied in many fields 数字全息术是一种新型的全息成像技术，具有广泛的应用范围。
Numerical reconstruction overcomes the shortcoming of optical method and helps to store and process images digitally 并且也便于图像的数字化存储和处理，有利于全息术的更广泛的应用。
According to the previous studies a new technique for recording hologram is proposed in this thesis 目前有关全息术的研究主要集中在对传统记录方法的改进和研究探讨其应用潜力和应用领域等方面。
( 2 ) the operation for numerical reconstruction of digital lensless fourier transform holography is experimentally presented ( 2 )从实验上讨论了利用数字无透镜傅里叶变换全息术数值再现全息图的具体过程。
Holography was one of the most important physical inventions in the last century . the british scientist dennis gabor brought the principle of holography firstly in 1948 全息术( holography )是上世纪最重要的物理发明之一，它的原理由英国科学家gabor于1948年最早提出。
However , digital lensless fourier transform holography has more outstanding strongpoints and better advantages for shape and deformation measurement of microstructures 其中数字无透镜傅里叶变换全息术具有更突出的优点，因此在微结构的形貌及形变测量方面具有很强的应用前景。
