چکیده

We employed amplitude and frequency modulated voltage in fast switching optical retarder with a high pretilt angle dual-frequency nematic cell. We obtained the response times 150 – 500 μs for an optical retardation shift on 0.3 – 2.2 μm in optical retarder with 12 μm thick nematic cell. The results could be used in beam steering, adaptive optics and display devices.

Fast Switching Dual-Frequency Liquid Crystal Optical Retarder, Driven by an Amplitude and Frequency Modulated Voltage

We demonstrate theoretically and experimentally a fast-switching nematic optical retarder capable to switch a few microns of optical retardation in less than 1 ms. For example, a nematic cell of thickness 14.5 mm switches 0.3 mm of retardation within 0.15 ms and 2.5 mm within 0.5 ms for single passage of beam. The corresponding figure of merit is two orders of magnitude higher than the one know...

Dual-Frequency Addressed Infrared Liquid Crystal Phase Modulators with Submillisecond Response Time

Dynamic response of a dual-frequency liquid crystal (DFLC) based near infrared phase modulator is investigated through numerical simulations and experiments. The relationships between the optical response times and various voltage driving conditions are studied. An optical phase retarder operating at 1.55 lm wavelength is demonstrated by using our homemade high figure-of-merit DFLC mixture. To ...

Fuzzy Logic Based Life Estimation of PWM Driven Induction Motors

Pulse-width modulated (PWM) adjustable frequency drives (AFDs) are extensively used in industries for control of induction motors. It has led to significant advantages in terms of the performance, size, and efficiency but the output voltage waveform no longer remains sinusoidal. Hence, overshoots, high rate of rise, harmonics and transients are observed in the voltage wave. They increase voltag...
