(18) This commercially-available optical biometer converts optical path length to AL, through an assumed average total eye refractive index.
According to the Beer-Lambert law, effective absorption optical path length L is a very important parameter in a TDLAS system.

Significant enhancement of the photovoltaic performance of the nanoimprinted solar cells was achieved due to effective light trapping and increase in optical path length from the textured active layer and efficient charge carrier collection from the buried nanostructured aluminum electrode.
In this paper, we will further analytically demonstrate that the vacuum polarization by the scalar field dark energy of 5D gravity can increase the relative optical path length (i.e.
The changes (contraction) occur and can be measured through the reaction of direct perturbation during a contraction or transfiguration of muscle, which these changes will affect the optical path length changes in the refractive index changes and the optical path length, which can be used to produce the required measurement parameters.
To improve sensitivity, the photometer was coupled to a flow cell with an optical path length of 200 mm.
where [bar.[C.sub.l]] is the liquid concentration; [L.sub.I] is the optical path length of the liquid phase spray and [[sigma].sub.ext]([[lambda].sub.V]) is the extinction coefficient of droplets at wavelength [[lambda].sub.V].
Other sensors measure the time of flight of the light while the physical property changes the optical path length.
From this measurement we can directly measure the optical path length of the egg shell.
The optical path length of the laser beam (i.e., wavelength [[lambda].sub.L]) changes by the refractive index variation when the laser beam is transmitted through the sound field.
Intense atmospheric turbulences caused a random error in the optical path length which probably would be a few centimeters at 10 degrees.
