  2. Electro-optical sensor - Wikipedia

    en.wikipedia.org/wiki/Electro-optical_sensor

    An optical sensor can measure the changes from one or several light beams. When a change occurs, the light sensor operates as a photoelectric trigger and therefore either increases or decreases the electrical output. An optical switch enables signals in optical fibers or integrated optical circuits to be switched selectively between circuits ...

  3. Electro-optics - Wikipedia

    en.wikipedia.org/wiki/Electro-optics

    Electro–optics is a branch of electrical engineering, electronic engineering, materials science, and material physics involving components, electronic devices such as lasers, laser diodes, LEDs, waveguides, etc. which operate by the propagation and interaction of light with various tailored materials.

  4. Electro–optic effect - Wikipedia

    en.wikipedia.org/wiki/Electro–optic_effect

    Electro-optic modulators are usually built with electro-optic crystals exhibiting the Pockels effect. The transmitted beam is phase modulated with the electric signal applied to the crystal. Amplitude modulators can be built by putting the electro-optic crystal between two linear polarizers or in one path of a Mach–Zehnder interferometer.

  5. Opto-electronic oscillator - Wikipedia

    en.wikipedia.org/wiki/Opto-electronic_oscillator

    In optoelectronics, an opto-electronic oscillator (OEO) is a circuit that produces a repetitive electronic sine wave and/or modulated optical continuous wave signals. An opto-electronic oscillator is based on converting the continuous light energy from a pump laser to radio frequency (RF), microwave or mm-wave signals.

    The company was founded in Ghent in 1919 () as Optique et Instruments de Précision (Precision Optics and Instruments), as an effort of Belgium to develop its own optical industry for its army. [ 1 ] From its foundation until the 1950s, OIP developed military lenses and objectives, medical and scientific microscopes, as well as cameras and ...
