摘要
基于菲涅耳波带板扫描全息术,提出了无运动卷积菲涅耳波带板扫描全息术。由于菲涅耳波带板扫描全息术经过二维电移台控制物体移动进行二维扫描,得到整个物体的扫描全息图,因此,它是通过物体的光强透过率函数与菲涅耳波带板的光强透过率函数的卷积得到物体的扫面全息图。这种方法的缺点是扫描时间长。无运动扫描全息术是根据几何光学的基本理论,无需物体的移动直接得到扫描全息图,大大缩短了扫描时间。
Fresnel Zone Plate (FZP) non-movable convolution scanning holography is based on the FZP scanning holography. The whole subject scanning hologram is obtained via the two-dimensional move of the subject controlled by dynamoelectric moveable platform in FZP scanning holography, Consequently, The scanning hologram of an object is the convolution of the transmittance of the object with the intensity distribution of the Fresnel zone plate. The shortcoming of this method is that the scanning time is too long. Non- movable scanning holography is based on the theory of geometry optics. The scanning hologram is obtained dispense with the move of the object. That can save the scanning time consumedly.
