ABSTRACT:
An apparatus and method to simultaneously measure electric and thermal fields with a single probe. Using an electrooptic semiconductor probe, the Pockels effect is employed to measure electric field magnitude and phase, and the effect of photon absorption due to bandtail states in the semiconductor is used to measure temperature. Techniques to scale relative electric-field measurements to absolute units (volts/meter), stabilize electric-field phase drift, and calibrate electric-field data that is corrupted when the probe is used in regions where temperature gradients exist are provided.
