3D printed diffractive optical elements for rapid prototyping

Micro and Nano Engineering
A rapid and robust method to fabricate transmission diffractive optical elements in the visible wavelengths is presented. By additive manufacturing of a polymeric photo-resin using 2-photon lithography followed by encasing of the structure in another ...

An improved algorithm for diffractive optical element with high imaging quality

Journal of the European Optical Society-Rapid Publications
An improved algorithm for diffractive optical element (DOE) with high imaging quality is proposed in this paper. The algorithm is designed based on amplitude division between signal and noise regions, further subdivides the noise region into two distinct
