Detection of Polymer Brushes developed via Single Crystal Growth
Single crystals consisting various surface morphologies and epitaxial structures were applied to investigate the effect of other phase regions in the vicinity of a given tethered chains-covered area having a certain molecular weight of amorphous brushes. The designed experiments demonstrated that regardless of the type of surface morphology (patterned and especial mixed-brushes, homo and co...
متن کاملHyperspectral Imaging with Liquid- Crystal Tunable Filter for Tissues Characterization
We developed and characterized a new near-infrared hyperspectral imaging system. The system consists of a charged coupled device and liquid crystal tunable filter, which is continuously tunable in the near-infrared spectral range of 650-1100 nm with a mean bandwidth of 5 nm. Experiments are conducted to quantitatively determine normal tissues characterization. In the first experiment, hyperspec...
متن کاملHyperspectral imaging with a liquid crystal polarization interferometer.
A novel hyperspectral imaging system has been developed that takes advantage of the tunable path delay between orthogonal polarization states of a liquid crystal variable retarder. The liquid crystal is placed in the optical path of an imaging system and the path delay between the polarization states is varied, causing an interferogram to be generated simultaneously at each pixel. A data set co...
متن کاملLiquid-crystal point-diffraction interferometer.
A new point-diffraction interferometer has been developed with a liquid-crystal filter that permits arbitrary phase shifts to be introduced between the object and reference beams. A microsphere embedded within the liquid-crystal layer provides a locally generated reference beam. We phase shift the object beam by varying a voltage across the liquid crystals, thereby altering the refractive index...
متن کاملImaging linear polarimetry using a single ferroelectric liquid crystal modulator.
In the field of polarimetry, ferroelectric liquid crystal cells are mostly used as bistable polarization rotators suitable to analyze crossed polarizations. This paper shows that, provided such a cell is used at its nominal wavelength and correctly driven, its behavior is close to that of a tunable half-wave plate, and it can be used with much benefit in lightweight imaging polarimetric setups....
