Here we study self-assembled of 9-diethylamino-5-benzo[α]phenoxazinone 9 . AFM, SEM, Raman imaging, studies demonstrate that such materials form micron-sized tub-like structures with rectangular shape. These microstructures show both active and passive wave guiding modes. Applying wavelengths in resonance 532 nm, and in non-resonance (785nm) with the molecular electronic absorption bands was undertaken for active and passive wave guiding studies. PL spectra capping point, the body and emerging light points were investigated. Meanwhile, Raman scattered photons were also acquired which maintain the polarized light propagation direction(s) and its interaction with tube molecules. The hollow features and tubes defect were identified using Raman imaging. These studies showing that excellent wave guiding features are present using these self-assembled micron-tube structures.
White mushrooms were subjected to mechanical injury by controlled shaking in a plastic box at 400 rpm for different
times (0, 60, 120, 300 and 600 s). Immediately after shaking, hyperspectral images were obtained using two pushbroom
line-scanning hyperspectral imaging instruments, one operating in the wavelength range of 400 - 1000 nm with
spectroscopic resolution of 5 nm, the other operating in the wavelength range of 950 - 1700 nm with spectroscopic
resolution of 7 nm. Different spectral and spatial pretreatments were investigated to reduce the effect of sample curvature
on hyperspectral data. Algorithms based on Chemometric techniques (Principal Component Analysis and Partial Least
Squares Discriminant Analysis) and image processing methods (masking, thresholding, morphological operations) were
developed for pixel classification in hyperspectral images. In addition, correlation analysis, spectral angle mapping and
scaled difference of sample spectra were investigated and compared with the chemometric approaches.
