Comparative analysis of the measurement methods for the wire's position using the TSL1410R optical sensor

In the dams monitoring procedure there are several important aspects that must be taken into consideration when the specialists must give a detail report regarding the construction behavior during the operation. One of the above physical phenomena that must be followed is the inclination of the concrete blocks during the freezing / unfreezing intervals or maximal / minimal loads (from the lake's water volume perspective) periods. That can be made using a dedicated sensor, a linear optical sensor with a large number of pixels that basically calculates the position of a wire, by its shadow position, by projecting it on the optical sensor using an area of powerful LEDs. The paper wants to identify the best method for the wire's position determination using the TSL1410R optical sensor from two points of view: the speed of the wire's position determination and the stability of the obtained results.
