Phase plates are widely used in optical polarization systems to change the state of polarization of a polarized beam to any required state or to determine the state of polarization. The simplest known method for calibrating a phase plate is the Senarmont method. The problem of this method is that the compensating plate must be of exact quarterwave retardance at the working wavelength which is very...
Polarization metrology is gaining increased importance as polarized light is recently involved in different branches of science and technology. This paper summarizes the contributions of the optical polarization laboratory at the National Institute for standards (NIS, Egypt) during the last 25 years. These include introducing a new class of total internal reflection phase retarders, modifying the...
In recent works, it was shown that the retardances δ1, and δ2 of two birefringent phase plates C1 and C2 could be measured simultaneously at any wavelength by a single adjustment of the optical system. If the two plates are identical (δ1=δ2=δ), the calibration process becomes more simple, quick, accurate and the expressions for evaluating δ are quite simple. Two mica plates of the same thickness d...
