Compensation of coherence effects in an optical spectrum analyzer
Abstract:
An optical technique is described which is capable of compensating the effects of imperfect spatial coherent illumination on the performance of a modified Mach-Zehnder spectrum analyzer. Methods for experimentally determining the complex mutual coherence function of the illumination using the analyzer are also described. The addition to the system of a calibrated phase shifter controlled by a minicomputer is proposed, which permits the spectral amplitude and phase to be determined automatically in real time.

¹H NMR: Interpreting Distorted and Overlapping Signals
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are slanted or...
Atomic Absorption Spectroscopy: Interference
Spectral interference occurs when signals from other elements or molecules overlap with the analyte signal, falsely elevating or masking the analyte's absorbance. This interference can be corrected using Zeeman,...

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
