diverging beam造句

• Since this solution relies on the paraxial approximation, it is not accurate for very strongly diverging beams.
• The zero-frequency ( DC bias ) component has no focal point, but overlays both the converging and diverging beams.
• :: : You mean take the diverging beam, make it converge to a point and then as its diverging, again use a lens of shorter focal length to make a narrower beam than the first lens produced?
• Thus, when the recorded pattern is illuminated with the original plane wave, some of the light is diffracted into a diverging beam equivalent to the original spherical wave; a holographic recording of the point source has been created.
• These two rotations are associated with two forms of angular momentum, namely SAM and OAM . However this distinction becomes blurred for strongly focused or diverging beams, and in the general case only the total angular momentum of a light field can be defined.
