CORRELATION LENGTH ESTIMATION ISSUES IN …

WebFor example, if the coherence length of a laser is 1 km, the phase relationship between two points along the laser beam, with a distance of 1 km between them, is still significant, but already substantially degraded by phase fluctuations of the laser. Figure 1: Setup of an interferometer, where the coherence length of light is important. WebDifferent correlation lengths were obtained depending on the used set of crystallographic orientations. We determined that the different sets of crystallographic orientations affect the general level of the correlation length, however, as the external load is increased the behaviour of correlation length is similar in all the analyzed cases.
