An Analysis of Cholesteric Spherical Reflector Identifiers for Object Authenticity Verification

چکیده
Arrays of Cholesteric Spherical Reflectors (CSRs), microscopic cholesteric liquid crystals in a spherical shape, have been argued to become game-changing technology anti-counterfeiting. Used build identifiable tags or coating, called CSR IDs, they can supply objects with unclonable fingerprint-like characteristics, making it possible authenticate objects. In previous study, we shown how extract minutiæ from IDs. this journal version, on that research, consolidate the methodology, and test over IDs obtained by different production processes. We measure robustness reliability our procedure large variegate sets IDs’ images taken professional microscope (Laboratory Data set) could be used realistic scenario (Realistic set). intra-distance interdistance, proving distinguish coming same ID However, without surprise, Laboratory set an average is less, less variance, than between responses Realistic set. With evidence, discuss few requirements for anti-counterfeiting based CSRs.

Enhancing cholesteric liquid crystal laser performance using a cholesteric reflector.
A high performance dye-doped cholesteric liquid crystal (CLC) laser is demonstrated by incorporating a passive CLC reflector to the active cell. The polarization-conserved CLC reflector effectively increases the distributed feedback cavity length which, in turn, results in a significant enhancement in lasing efficiency and a dramatic reduction in beam divergence. The lasing characteristics are ...
متن کاملExperimental Investigation of Laser Emission of Dye-Doped Cholesteric Liquid Crystals with a Cholesteric Reflector
Dye-doped cholesteric liquid crystal (CLC) behaves like a one-dimensional photonic crystal laser when pumped by a second harmonic Nd-YAG pulsed laser. Usually circularly polarized laser light in the same sense as the cholesteric helix is emitted from both directions of the lasing cell. In this paper, we experimentally demonstrate the laser emission enhancement and investigate the corresponding ...

an infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
