Whitaker %J Sensors %D 2011 %I MDPI AG %R 10.3390/s110100806 %X In this paper we review recent design methodologies for fully dielectric electro-optic sensors that have applications in non-destructive evaluation (NDE) of devices and materials that radiate, guide, or otherwise may be impacted by microwave fields. In many practical NDE situations, fiber-coupled-sensor configurations are preferred due to their advantages over free-space bulk sensors in terms of optical alignment, spatial resolution, and especially, a low degree of field invasiveness. We propose and review five distinct types of fiber-coupled electro-optic sensor probes. The design guidelines for each probe type and their performances in absolute electric-field measurements are compared and summarized. %K microwave measurement %K electro-optic measurement %K optical sensing %K sensors %U http://www.mdpi.com/1424-8220/11/1/806
