Diffraction gratings are curious things. Score a series of equally spaced tiny lines in a surface, and it will cause reflected or transmitted light to bend and separate into its component wavelengths.

This book presents a comprehensive tutorial on propagation, diffraction and scattering problems from the basic principles of physical optics. Beginning with the fundamental differential and integral ...

Abstract: We fabricate 3D gratings and diffraction optics using direct laser writing. Diffraction patterns of gratings agree with Laue theory. We demonstrate zone plates for visible wavelengths.

Abstract: The properties of imaging systems can be described by the point-spread function, which is determined by diffraction. A shorter wavelength results in a smaller diffraction pattern and ...

Scientists at Samara National Research University have been successfully working in the field of diffraction optics and nanophotonics, developing new optical elements for use in space, agriculture and ...
