Abstract: Recent advances in diffractive optics theory and technology have
made beam splitting a valuable resource for optical designers.
Programmable, multichannel optical systems can be designed
based on diffraction gratings, lenslet arrays and digital holography
algorithms. Spot array generation, multiple and multifocal imaging,
matched filtering, laser beam mode selection and simultaneous
contour shaping are among the most promising applications of
diffractive beam splitting today.
