摘要： A Raman method and system for analysing a sample including an excitation source emitting an incident light beam, a sample holder for mounting the sample, elements for focusing the incident light beam onto the sample surface to generate a Raman scattered light having an intensity, elements for collecting the Raman scattered light to form a Raman scattered light beam, a detection system measuring intensity of the Raman scattered light beam as a function of time. The system includes at least a polarization state generator able to generate four independent polarization states or a polarization state analyzer able to analyze four independent polarization states to detect the intensity of the Raman scattered light beam and calculate a partial or complete Mueller-Stokes matrix of the sample.

摘要： This invention concerns a spectroscopic ellipsometer modulated at a frequency (.omega..sub.m) intended for taking measurements of a sample (3). The spectroscopic ellipsometer is phase modulated, the sample being excited by external means (16) producing periodic, alternating excitation at a frequency (.OMEGA..sub.e). The measurement contains the ellipsometric parameter values (.psi., .DELTA.) of the sample, respectively in the presence of (.psi..sub.1, .DELTA..sub.1) and in the absence of (.psi..sub.2, .DELTA..sub.2) excitation of the sample, as a function of excitation frequency (.OMEGA..sub.e).
