Abstract:   (14773 Views)
We introduced a new method based on Fresnel diffraction from phase step for Fourier Transform spectroscopy. In contrast to interferometry that the optical path difference (OPD) is changed by displacing one of interferometer mirrors, in this method the OPD is changed by varying the angle of the incident light on the step. Since, the angle can be varied from 0-90 degrees in each experiment, there is a large volume of experimental data for the evaluation of the results. This increases the accuracy of the measurements, particularly, for broadband light sources. The introduced method is applied to the measurements of spectral line width and to the specification of line shape of an LED with mean wavelength of 620nm.
