Rev Sci Instrum
. 2025 Jan;
96(1.
PMID: 39841065
We demonstrate a broadband implementation of coherent Fourier scatterometry (CFS) using a supercontinuum source. Spectral information can be resolved by splitting the incident field into two pulses with a variable...

Phys Rev Lett
. 2024 Dec;
133(23):233803.
PMID: 39714683
Chiral objects are abundant in nature, and although the enantiomers have almost identical physical properties apart from their handedness, they can exhibit significantly different chemical properties and biological functions. This...

Kotte T, Adam A, Zuidwijk T, Heerkens C, Xu M, Urbach H
Opt Express
. 2023 Nov;
31(23):38815-38830.
PMID: 38017976
We study the broadband scattering of light by composite nanoparticles through the Born approximation, FEM simulations, and measurements. The particles consist of two materials and show broadband directional scattering. From...

Opt Express
. 2020 Jul;
28(14):20660-20668.
PMID: 32680121
Improving the image quality of small particles is a classic problem and especially challenging when the distance between particles are below the optical diffraction limit. We propose a imaging system...

PMID: 32543591
Diffractive shearing interferometry (DSI) is a method that has recently been developed to perform lensless imaging using extreme ultraviolet radiation generated by high-harmonic generation. In this paper, we investigate the...

. 2019 Sep;
58(22):5916-5923.
PMID: 31503906
Scatterometry is an important nonimaging and noncontact method for optical metrology. In scatterometry certain parameters of interest are determined by solving an inverse problem. This is done by minimizing a...
