Title
Bifrequency Pendulum On A Rotary Platform To Teach Optical Birefringence And Liquid Crystalline Displays
Abstract
Bifrequency pendulum on a rotary platform was tested and used for several years as a tool to teach various optical phenomena, mostly connected with the polarization of light waves. The following optical topics have found their mechanical analogs: linearity and superposition; damping; isotropy versus anisotropy; birefringence, uniaxial crystals; adiabatic following versus abrupt changes; liquid crystalline displays for watches, based on a twisted nematic cell; quantum-mechanical level anti-crossing; center-symmetric (χ(3)) nonlinearity and self- rotation of polarization ellipse; angular momentum conservation; non- center-symmetric (χ(2)) nonlinearity and second harmonic generation. This pendulum continues to serve as a source of ideas for new optical devices.
