The effects of electronic microscanning on infrared image aliasing and spaial resolution
Most modern infrared electro-optical imaging systems utilize staring imagers to acquire image data. Typical staring focal plane arrays contain a two-dimensional array of photodetectors. Each photodetector generates an electrical current or charge proportional to the number of photons striking its …

Three Dimensional Television : An Investigation Concerning Programmable Parallax Barriers
… of images is a logical step in the evolution of electronic display systems. We see the world stereoscopically so it is only natural that representations of this experience should provide an equally rich visual sensation. There have been countless attempts to produce an effective three dimensional …

Electro-Optic Properties of Self-Assembled Non-Linear Optical Polymers
Electrostatic self-assembly was used to fabricate several samples of polymers known to have non-linear optical behavior. These samples characteristics were measured with interferometry and their electro-optic coefficients determined to be on the order that of LiNbO3. The self-assembled samples are …

Interactions of Organic Fluorophores with Plasmonic Surface Lattice Resonances
… various wavelengths are a function of the metal electronic band structure. Metals that have both an abundance of mobile (“free”) valence electrons and an abundance of vacant states in the valence band are able to support propagating oscillations in the free-electron density, much like sound waves …
