“…On the free boundary, the stable director orientation is perpendicular to the air–liquid crystal boundary. Such a case has been described in several papers [ 11 – 17 ] and the stable director field structure has been calculated in the SmA phase. The pattern of the SmA free boundary shown in of Figures 2–4 is similar to the experimental observations in [ 3 – 8 ] and calculations in [ 8 , 11 – 14 ].…”

This work presents the first high-resolution nanoprofilometry study consisting of nanoscale resolution surface profile measurements and high-quality visualization of a the free surface of a liquid crystal–air boundary. The capabilities of this new experimental method, as applied for liquid crystal free boundaries, are discussed. The formation of focal conic domain structures at the smectic-A–air free boundary was detected and studied.

“…The measurement itself is relative to the measurement using a CCD camera, less time-consuming and does not require the use of complex algorithms. This is a completely new tool for phase measurements adapted for liquid crystal (LC) materials [11].…”

In a depolarizing instrument, such as a broadband imaging spectrometer, the depolarizers are placed on the system for stabilization the optical signal. They are also used to reduce measurements offsets due to strong polarization dependence, which produce drastic deterioration of the signal to noise ratio. Dynamic depolarizer with a controllable degree of polarization is also required to study the effect of noise on quantum information. The article described a new instrument for characterization the variable depolarizer with features which make it different from a polarimetric system. The analysing system based on the simple structural design and has good stability for real-time measurement. A practical application of the described interferometer system for variable depolarizer characterization is also presented.
