A system and method for improving data provided by ellipsometer, polarimeter and the like systems involving diminishing the effects of undesirable noise in the intensity of a beam of electromagnetic radiation caused by, for instance, random variations in intensity of a source provided beam of electromagnetic radiation and/or periodic or non-periodic variations in beam intensity resulting from wobble/wander of a moving sample, during investigation of the sample by the beam of electromagnetic radiation. |
