    abstract = {This research attempts to study the behavior of the Helium-Neon laser spot by using a digital camera
and passing through various physical media (distilled water, water of the Tigris River of Iraq-Wasit) to study
its properties and develop equations that describe this behavior for several readings by calibrating them with
TDS device. The equation by which a system can predict the behavior of a laser spot is calculated depend on
the changing of the intensity of the resulting laser spot where a relationship is found between the intensity
of the laser spot and the amount of concentrations of dissolved molecules in liquids and calculating the
deposition time of the suspended materials. The final results showed the linear relationship between deposition
time and intensity as well as deposition time and the readings of the TDS water system of the Tigris River, the
results showed that it is possible to study the behavior of the laser spot when passing through different media
and to find a mathematical relationship to describe and predict the results. This behavior is described by
studying the intensity with concentrations of different materials and within different media. The deposition time
was also calculated for different media based on the same principle. This was done by a system were build and
a multiple software’s such as ImageJ, Origin Lab 9.0, MATLAB R2013b and CurveExpert Professional 2.6.5.}
