摘要
单色平行光照明全息双频位相光栅,1级衍射的直条纹投射到物体上,在另一相同光栅的1级衍射像中出现莫尔条纹.
The 1st order straight fringes,diffracted from holographic double-frequency phase grating illuminated by monochromatic collimated beam,areprojected onto the object.The Moire fringes appear in the 1st diffractionimage of the other same grating.
