When the laser beams project in the relief gratings, its transmissiondiffraction patterns represent the surface informations of the relief gratings.
当激光束投射在浮雕光栅上,透过光栅的衍射光斑就反映了浮雕光栅的表面信息。

The resultant surfaces were characterized by means of SEM, transmission electron microscopy (TEM), X-ray diffraction (XRD), and water contact Angle measurements.
用扫描电镜、透射电镜、X射线衍射、接触角测量等技术对表面进行了表征。

A properly choiced bias transmittance of the hologram can lead to a diffraction efficiency close to or a little higher than that of transmission reconstruction.
