distinguish optoelectronics Electro optics is a branch of technology involving components, devices and systems which operate by modification of the optical properties of a material by an electric field . Thus it concerns the interaction between the electromagnetism electromagnetic optics optical and the electricity electrical electron ic states of materials. Electro optical devices The electro optic effect relates to a change in the optical properties of the medium which usually is a change in the birefringence and not simply the refractive index. In a Kerr cell , the change in birefringence is Proportionality mathematics proportional to the square of the electric field , and the material is usually a liquid. In a Pockels cell , the change in birefringence varies linearly with the electric field, and the material is a crystal. Non crystalline electro optic material have caught interested because of their low cost of production. It is polymer based material, therefore is organic material. It is called sometimes as organic EO material, plastic EO material, or polymer EO material, which consists of a polymer and a nonlinear optical chromophore. Nonlinear optical chromophore is the molecule has Pockel s effect.

Cleanup date October 2010 Optical aberration In optics , piston is the mean value of a wavefront or Phase waves phase profile across the pupil of an optical system. The piston coefficient is typically expressed in wavelength s of light at a particular wavelength . Its main use is in curve fitting wavefronts with Cartesian polynomials or Zernike polynomials . However, similar to a real V8 engine piston moving up and down in its cylinder, optical piston values can be changed to Bias electrical engineering bias the wavefront phase mean value as desired. As phase values can only vary from zero to 2 , then repeat in either direction termed phase wrapping , changing the piston coefficient changes the zero phase value contour locations across the wavefront. This property is critical to the operation of phase measuring interferometers , which give not only the magnitude but also the sign wikt convexity convexity or wikt concave concavity of a wavefront under test. Piston is physically created in the interferometer by piezoelectric actuators that translate the Fizeau interferometer reference surface along the optical axis by precise fractions of the test wavelength, usually by one quarter of a wavelength. This changes the interferometric fringe patterns and allows direct calculation of the exact wavefront error. Piston and Tilt optics tilt are not actually true optical aberration optics aberrations , as they do not represent or model curvature in the wavefront. Defocus is the lowest order true optical aberration. If piston and tilt are subtracted from an otherwise perfect wavefront, a perfect, aberration free image is formed.
