Second, it is suggested that variations of transmittance are subjected to exponential decay, which is well explained by the principle of the Christiansen effect. And such observation of transmittance shall provide approaches to improving transparency quality of transparent soil.
Principle of the Christiansen Effect. To investigate the variation in transmittance of transparent soil and to analyze the qualitative relationship between the factors (that affect the variation in transmittance) and the transmittance, the principle of Christiansen effect is proposed for the curve fitting of experimental results of transmittance of transparent soil.
The principle of the Christiansen effect is the theoretical basis of this research that explains the factors that affect transmittance in optical measurements of transparent soil.
In general, the impact of refractive index matching is well described by the exponential decay of principle of the Christiansen effect.
Additionally, analysis of transparent soil property and the principle of the Christiansen effect are integrated in this paper.
* It does not suffer from the Christiansen effect (band distortion from changes in index of refraction in regions of an absorption band) observed when using KBr pellets and mulls.
