2009/6/8
A computer generated hologram (CGH) is a useful tool for various optical applications, such as beam multiplexing, patterning, beam homogenizer, etc. The precise technologies are important issue for th...
Beam shaping based on intermediate zone diffraction of a micro-aperture
aperture diffraction beam shaping
2011/5/6
We analyze optical diffraction of a micro-aperture (slit or hole) in a metal screen in the intermediate zone and report its application for beam focusing and collimating in micro-optics. Both finite-d...
