Abstract:
1. A method for determining a refractive index, the method comprising: a) providing an amount of matter in a form of at least one pattern of a theoretically measurable diffraction pattern and a theoretically measurable scattering pattern; b) defining at least two orders of diffraction from the at least one pattern to form at least one intensity ratio; c) generating at least one intensity distribution by irradiating the at least one pattern using a light beam of a defined form; d) forming the at least one intensity ratio using the at least two orders of diffraction of the at least one intensity distribution; e) determining at least one portion of a characteristic curve of a functional relationship between the at least one intensity ratio and the refractive index; and f) assigning the at least one intensity ratio to the refractive index using the characteristic curve.
