Based on the Pockels Effect (interaction between an electric field and a laser beam), the non-perturbative optical technology of KAPTEOS is the result of fifteen years of research and development. Their award-winning technology enables customers to carry out interference-free and real-time electric field measurements with great accuracy in vacuum, liquids, biological media and also under high voltage, high pressure, X-rays, gamma rays, i.e. usually referred to as harsh environment.
Even if the Pockels effect has been discovered in the nineteenth century (1893), the major innovation by KAPTEOS is the use of the laser polarization state as the information carrier for the electric field. This technology has been patented by KAPTEOS founders in 2006: it allows to make accurate and reliable measurements regardless the temperature (measurement repeatability of 0.15 dB, no matter the environmental conditions), unlike other methods, either based on phase modulation or amplitude modulation, as used in competing technologies
