Paper Abstract
This paper shows the qualitative and quantitative results obtained on the test of cylindrical parabolic concentrators when
the screens are designed using dot color changes to guarantee a better dot correspondence assignment and to make the
optical test of the concentrator easier; the method allows to measure deformations from tenths of a millimeter to several
millimeters, thus demonstrating that null screen method is good enough for testing surfaces with important deformations.
On a second approximation, it is designed a null screen corresponding to the surface evaluated with the first one by
fitting a fourth grade polynomial with crossed terms; with this, it is shown that the first test gets closer to the shape of the
surface validating it.
