Measuring Agarwood Formation Ratio Quantitatively by Fluorescence Spectral Imaging Technique
Agarwood is a kind of important and precious traditional Chinese medicine. With the decreasing of natural agarwood, artificial cultivation has become more and more important in recent years. Quantifying the formation of agarwood is an essential work which could provide information for guiding cultivation and controlling quality. But people only can judge the amount of agarwood qualitatively by ...
متن کاملFluorescence Ratio Imaging
In this paper, the properties of the mean and variance of three estimators of the ratio between two random variables x, y are discussed. Given n samples of x and y we can construct two different estimators. One is biased and the other is asymptotically unbiased. Using the noise characteristics (variance, covariance) a third, unbiased estimator can be constructed. 1. Introduction In fluorescence...
متن کاملSpectral imaging fluorescence microscopy.
The spectral resolution of fluorescence microscope images in living cells is achieved by using a confocal laser scanning microscope equipped with grating optics. This capability of temporal and spectral resolution is especially useful for detecting spectral changes of a fluorescent dye; for example, those associated with fluorescence resonance energy transfer (FRET). Using the spectral imaging ...
متن کاملDevelopment of Fluorescence Spectral Imaging
Since the 1980’s, depleted uranium (DU) has been the primary material used by the US military in armorpiercing rounds. Domestic firing ranges that have been used for DU munitions training purposes are located around the country and have varying extents of contamination by other types of projectiles. A project is underway to develop a set of sensors to locate expended DU rounds and to process so...
متن کاملWhole-tree agarwood-inducing technique: an efficient novel technique for producing high-quality agarwood in cultivated Aquilaria sinensis trees.
Agarwood is the fragrant resin-infused wood derived from the wounded trees of Aquilaria species. It is a valuable non-timber forest product used in fragrances and as medicine. Reforestation for Aquilaria trees in combination with artificial agarwood-inducing methods serves as a way to supply agarwood and conserve of wild Aquilaria stock. However, the existing agarwood-inducing methods produce p...
