OPTICAL MEASURING DEVICE OPERATING ACCORDING TO THE POCKELS EFFECT PRINCIPLE FOR ELECTRICAL FIELD STRENGTH/VOLTAGE MEASUREMENT WITH MINIMUM TEMPERATURE-DEPENDENCE
摘要
<p>In a optical measuring device for measuring electrical fields/voltages with electrically optical double refraction (Pockels effect) a Fresnel rhombus (14) is used as the circular polarizer μ/2-phase shifter.</p>
