To measure the velocity of light in water and Perspex and thereby determine the refractive indices for these substances. Experimental Background Consider a source that emits light with a periodic time dependent intensity of the form )2cos()(0ft I t I . [1]If this signal is detected by ...
PURPOSE:To perform measurement in a wide dynamic range, by quickening the integral time of a photocurrent when the intensity of receiving light is low and making the same long when said intensity is high. CONSTITUTION:At first, a control circuit 6 brings a rest transistor Tr4A to a ...

Measurements of the autocorrelation function and average intensity of light quasielastically scattered from aqueous solutions of sodium dodecyl sulfate (SDS) in the presence of added NaCl were carried out over a wide region of the micell... Norman,A.,Mazer,... - 《J.phys.chem》 被引量: 424...
Lasers and light-emitting diodes are used for a range of biomedical applications with many studies reporting their beneficial effects. However, three main
(rr,θ)is the cologarithm of the ratio of X-ray intensity at pixelrrto the flat-field at the same position. Frompref, one may compute a 3D image where each voxelxxis characterized by its coefficient of X-ray absorption,f(xx). This image is computed (or reconstructed) from the ...
The breakdown voltage's control pulse decreases with lower AFRs and larger areas of the initial flame kernels. Both effects result in lower local density between the electrodes. On the one hand, lower λ results in higher local temperatures and, therefore, lower density. On the other hand, a...
In this manuscript, we studied the thermal properties of hundred-watt fiber laser oscillator by real-time in-situ distributed temperature measurement. Optical frequency domain reflectometry (OFDR) was introduced to measure the temperature distribution of gain fiber core. The fiber laser oscillator operate...
Elimination of laboratory ozone leads to a dramatic improvement in the reproducibility of microarray gene expression measurements The cyanine dye Cy5 is subject to ozone (03) oxidation resulting in a decrease in fluorescence intensity [4]. Because two-color microarray experiments ... WS Branham,CD ...
Mie’s theory33,34. It predicts the scattering intensity induced by particles, irrespective of the fact whether they are transparent or opaque. LD particle size analyzers that use Mie’s theory (e.g., Mastersizer) base their particle size calculation on the assumption that particles are ...
