面全息图 meaning in Chinese

surface hologram

In order to investigate the phenomenon that holograms tend to be deteriorated on baing recorded in photopolymers with shrinkage , a fourier hologram is taken with slant gratings formed by the reference beam and object beams of different space - frequency
摘要为了分析光致聚合材料记录的谱面全息图在再现过程中发生“擦除”现象，将谱面全息图看作由不同角谱的物光与参考光在光致聚合材料内形成的不同倾斜角度的光栅总和。
The unfocused hologram of lensless fourier holography are also discussed , and a way to revise the reconstruction image of unfocused hologram is presented . ( 2 ) the reconstruction of image plane hologram is analyzed by plane wave theory . the image plane holograms of transparent and opaque objects are also obtained by using fibers
( 2 )用角谱理论分析了像面全息图的再现过程，采用光纤传光分别拍摄了透射和反射物体的像面全息图，并利用频域法对全息图进行数值再现，得到了物体较清晰的再现像。
