    Abstract: The method of measuring viscosity of a body exploits the scattering effects the body introduces into a substantially monochrmatic radiation passing through it; more paticularly, the width of the spectral line due to Brillouin scattering is measured. The temperature of the body can be determined too, by measuring also the width of the line generated by Rayleigh scattering. The method is of particular interest for measurements on glasses.

    Abstract: The radiation to be analysed is sent onto an interference filter (6) which selects different portions of the radiation spectrum in correspondence with different incidence angles. The intensity values of the radiation outgoing from the element (6) are stored by a measuring and data processing unit (9) which processes such values with the transfer function of the element to obtain the information on the spectrum.

    Abstract: A static interferometric ellipsometer, wherein a source (3) generates a coherent light-beam with two monochromatic radiations at slightly different frequencies. A first photodetector (6) generates a first beat between the two radiations, to be used as reference. A second photodetector (9) generates a second beat between the two radiations, after they have been polarized in perpendicular planes and separated so that one of them is reflected onto the photodetector (9) by the sample under test (1,2). A measuring and computing system (11) determines the optical properties of said sample starting from the intensity of the second beat and from the relative phase between the two beats.
