Volumetric Light-Field Excitation
We explain how to concentrate light simultaneously at multiple selected volumetric positions by means of a 4D illumination light field. First, to select target objects, a 4D imaging light field is captured. A light field mask is then computed automatically for this selection to avoid illumination of the remaining areas. With one-photon illumination, simultaneous generation of complex volumetric...
متن کاملVolumetric Light-field Encryption at the Microscopic Scale
We report a light-field based method that allows the optical encryption of three-dimensional (3D) volumetric information at the microscopic scale in a single 2D light-field image. The system consists of a microlens array and an array of random phase/amplitude masks. The method utilizes a wave optics model to account for the dominant diffraction effect at this new scale, and the system point-spr...
متن کاملRaycasting of Light Field Galleries from Volumetric Data
The paper describes a technique to generate high-quality light field representations from volumetric data. We show how light field galleries can be created to give unexperienced audiences access to interactive high-quality volume renditions. The proposed light field representation is lightweight with respect to storage and bandwidth capacity and is thus ideal as exchange format for visualizatio...
متن کاملEliminating unwanted far-field excitation in objective-type TIRF. Part I. identifying sources of nonevanescent excitation light.
Total internal reflection fluorescence microscopy (TIRFM) achieves subdiffraction axial sectioning by confining fluorophore excitation to a thin layer close to the cell/substrate boundary. However, it is often unknown how thin this light sheet actually is. Particularly in objective-type TIRFM, large deviations from the exponential intensity decay expected for pure evanescence have been reported...
متن کاملfor : Aperture interference and the volumetric resolution of light field fluorescence microscopy
This document provides supplementary information to ‘Aperture interference and the volumetric resolution of light field fluorescence microscopy’. We provide more information about: the derivation of the defocus OTF, additional ALF-ring schemes, frequency space invertibility, the forward model and reconstruction algorithm, and Monte Carlo simulations for calculating noise thresholds. In addition...
