Volume extreme ultraviolet nano-holographic imaging with numerical optical sectioning

Volume extreme ultraviolet nano-holographic imaging with numerical optical sectioning.

Three dimensional images were obtained using a single high numerical aperture hologram recorded in a high resolution photoresist with a table top lambda = 46.9 nm laser. Gabor holograms were numerically reconstructed over a range of image planes by sweeping the propagation distance in the numerical reconstruction algorithm, allowing numerical optical sectioning. A robust three dimension image o...

Real-time hyperspectral imaging with volume holographic optical elements

We report a novel hyperspectral optical sensor capable of providing image information with four degrees of freedom (4D), i.e. volumetric spatial information and spectral information simultaneously, in real time. The imaging principle is based on the diffraction properties of volume holographic optical elements designed as spatial-spectral filters. The 4D imager can be configured to image object...

Two and Three Dimensional Extreme Ultraviolet Holographic Imaging with a Nanometer Spatial Resolution

Volume holographic hyperspectral imaging.

A volume hologram has two degenerate Bragg-phase-matching dimensions and provides the capability of volume holographic imaging. We demonstrate two volume holographic imaging architectures and investigate their imaging resolution, aberration, and sensitivity. The first architecture uses the hologram directly as an objective imaging element where strong aberration is observed and confirmed by sim...
