Z-Scan method for measurement of bovine serum albumin concentrations
The changes in the nonlinear refractive of Bradford reagent caused by its binding to bovine serum albumin (BSA) were investigated in aqueous solutions. The nonlinear refractive index at the wavelength of 514 nm was measured using Z-scan Technique. The presence of BSA shows an increase of the nonlinear refractive index coefficient over Bradford reagent alone. The nonlinear refractive index the B...
متن کاملZ-polarized confocal microscopy.
In light microscopy the transverse nature of the electromagnetic field precludes a strongly focused longitudinal field component, thus confining polarization spectroscopy and imaging to two dimensions (x,y). Here we describe a simple confocal microscopy arrangement that optimizes for signal from molecules with transition dipoles oriented parallel to the optic axis. In the proposed arrangement, ...
متن کاملPhotoexcited Carrier Lifetime and Refractive Nonlinearity in Direct and Indirect Band Gap Crystals on the Z-Scan Technique
The Photoexcited carrier lifetime (τ) and peak to valley transmission difference (ΔTp-v) in direct and indirect band gap crystals has been investigated by the use of single beam open and closed aperture z-scan technique using frequency doubled Nd:YAG laser. The peak to valley transmission difference (ΔTp-v) is found to be of the order of 10-2 in case of direct band gap crystals and of the order...
متن کاملZ-scan formula for two-level atoms
An analytical expression for the Z-scan signal from two-level atoms which show a saturable dispersive and absorptive nonlinearity is derived. An approximate solution is obtained for the normalized transmittance and compared with numerical calculations. 2004 Elsevier B.V. All rights reserved.
متن کاملThe Bounced Z-buffer for Indirect Visibility
Synthesizing images of animated scenes with indirect illumination and glossy materials at interactive frame rates commonly ignores indirect shadows. In this work we extend a class of indirect lighting algorithms that splat shading to a framebuffer – we demonstrate deep screen space and ambient occlusion volumes – to include indirect visibility. To this end we propose the bounced z-buffer: While...
