Selection of operating wavelength‐pair for two‐wavelength microspectrophotometry

American Journal of Anatomy, 1976
AbstractThe two‐wavelength method is the microspectrophotometric method of choice for thick specimens. Its accuracy is dependent on the accuracy of selection of the operating wavelength‐pair. The “slope zero test,” offered as a check upon the accuracy of this selection (Garcia and Iorio, ′66) is shown to be invalid by analysis of experimental data, by ...

Dual-wavelength phase-shifting digital holography selectively extracting wavelength information from wavelength-multiplexed holograms.

Optics Letters, 2015
Dual-wavelength phase-shifting digital holography that selectively extracts wavelength information from five wavelength-multiplexed holograms is presented. Specific phase shifts for respective wavelengths are introduced to remove the crosstalk components

Plasma resonance enhancement of Raman scattering by pyridine adsorbed on silver or gold sol particles of size comparable to the excitation wavelength

, 1979
Intense Raman scattering by pyridine molecules adsorbed on silver or gold aqueous sol particles of dimensions comparable to the wavelength is reported. The degree of intensity enhancement is strongly dependent on the excitation wavelength, with a sharp ...

A heuristic wavelength assignment algorithm for multihop WDM networks with wavelength routing and wavelength reuse

Proceedings of INFOCOM '94 Conference on Computer Communications, 2002
The authors present a heuristic algorithm for effectively assigning a limited number of wavelengths among the access stations of a multihop network wherein the physical medium consists of optical fiber segments which interconnect wavelength-selective optical switches.

Two-Wavelength Interferometry

Applied Optics, 1973
Previous methods of two-wavelength variable-sensitivity interferometry are reviewed and a simplified two-wavelength technique for interferometric testing under static conditions is discussed. An extension of the static technique to real-time dynamic testing is proposed and an operational variable-sensitivity interferometer utilizing the real-time ...
