Query: New ellipsometric approach for determining small light ellipticities   We propose a precise ellipsometric method for the investigation of coherent
light with a small ellipticity. The main feature of this method is the use of
compensators with phase delays providing the maximum accuracy of measurements
for the selected range of ellipticities and taking into account the
interference of multiple reflections of coherent light. The relative error of
the ellipticity measurement in the range of mesurement does not exceed 0.02.
