As interest in anisotropic particles has increased in various research fields, methods of tracking such particles have become increasingly desirable. Here, we present a new and intuitive method to monitor the Brownian motion of a nanowire, which can construct and visualize multi-dimensional motion of a nanowire confined in an optical trap, using a dual particle tracking system. We measured the ...

For the advancement in multi-stimuli responsive optical devices, we report the elaborate molecular engineering of the dual photo-functionalized amphiphile (abbreviated as AZ1DA) containing both a photo-isomerizable azobenzene and a photo-polymerizable diacetylene. To achieve the efficient photochemical reactions in thin solid films, the self-assembly of AZ1DA molecules into the ordered phases s...

This paper describes an approach we suggest to monitor pavements by using an active optical device. Basically, the amount of light received by such sensors depends on superficial conditions, for which studying some specific traits of scattering indicatrices can bring substantial information. With this objective in sight, the major physical processes originating in the observed back-scattering a...

It is shown that by taking advantage of the superposition property of optical signals, one can further improve the performance of optical symbolic substitution processors.

Optical Code Division Multiple Access (OCDMA) has bright future in communication because of its faster speed, efficiency, security and unlimited bandwidth. To reduce Multiple Access Interface (MAI) and Phase Induced Intensity Noise (PIIN) noises there are many codes in Spectral Amplitude Coding-Optical Code Division Multiple Access (SAC-OCDMA) with codes best property i.e., minimum cross-correl...
