• #### Deviation Influences on Sectional Image Reconstruction in Optical Scanning Holography Using A Random-Phase Pupil ﻿

(Optical Society of America, 2013-10-01)
In this paper, we analyze the influence of two kinds of deviation errors on sectional image reconstruction for an optical scanning holography system using a random-phase pupil. The first deviation occurs in the lateral ...
• #### Differentiating between cancer and normal tissue samples using multi-hit combinations of genetic mutations ﻿

(Nature Publishing Group, 2019-01-30)
Cancer is known to result from a combination of a small number of genetic defects. However, the specific combinations of mutations responsible for the vast majority of cancers have not been identified. Current computational ...

• #### Digital Spectral Separation Methods And Systems For Bioluminescence Imaging ﻿

(Optical Society of America, 2008-01-01)
We propose a digital spectral separation (DSS) system and methods to extract spectral information optimally from a weak multispectral signal such as in the bioluminescent imaging (BLI) studies. This system utilizes our ...
• #### Direct observations of a surface eigenmode of the dayside magnetopause ﻿

(Nature Publishing Group, 2019-02-12)
The abrupt boundary between a magnetosphere and the surrounding plasma, the magnetopause, has long been known to support surface waves. It was proposed that impulses acting on the boundary might lead to a trapping of these ...
• #### Direct observations of the role of convection electric field in the formation of a polar tongue of ionization from storm enhanced density ﻿

(American Geophysical Union, 2013-03-01)
We examine the relationship of convection electric fields to the formation of a polar cap tongue of ionization (TOI) from midlatitude plumes of storm enhanced density (SED). Observations from the geomagnetic storm on 26-27 ...
• #### Dislocation-pipe diffusion in nitride superlattices observed in direct atomic resolution ﻿

(Springer Nature, 2017-04-06)
Device failure from diffusion short circuits in microelectronic components occurs via thermally induced migration of atoms along high-diffusivity paths: dislocations, grain boundaries, and free surfaces. Even well-annealed ...
• #### Displaying a high-resolution digital hologram on a low-resolution spatial light modulator with the same resolution obtained from the hologram ﻿

(Optical Society of America, 2013-07-01)
In this paper, a fast method for displaying a digital, real and offaxis Fresnel hologram on a lower resolution device is reported. Preserving the original resolution of the hologram upon display is one of the important ...
