“…Otherwise, to the best of our knowledge, there has been no report on the scanning free method for the H-MWNF imaging. The reported sensitivity of the scanning method based on the magneto optical effect with an optical scanning probe is around 0.03 mW10. However, this sensitivity is achieved by a noise reduction of the measurement system, and the MO effect by the H-WMNF is extremely weak so that it cannot be detected by a typical CCD camera16.…”

A high resolution imaging of the temperature and microwave near field can be a powerful tool for the non-destructive testing of materials and devices. However, it is presently a very challenging issue due to the lack of a practical measurement pathway. In this work, we propose and demonstrate experimentally a practical method resolving the issue by using a conventional CCD-based optical indicator microscope system. The present method utilizes the heat caused by an interaction between the material and an electromagnetic wave, and visualizes the heat source distribution from the measured photoelastic images. By using a slide glass coated by a metal thin film as the indicator, we obtain optically resolved temperature, electric, and magnetic microwave near field images selectively with a comparable sensitivity, response time, and bandwidth of existing methods. The present method provides a practical way to characterize the thermal and electromagnetic properties of materials and devices under various environments.

“…Meanwhile, high sensitivity [2], [3] and extremely low invasiveness [4], [5] are achieved in conventional single-channel systems. It is expected that LEI systems will be used for high-speed imaging under various conditions, and details of the electromagnetic field will be measured with single-channel systems.…”

We report on 100 100 pixel live electrooptic imaging (LEI), which is real-time imaging of electrical signals on a microwave circuit. The circuit's electric near-fields can be depicted in real time on a display screen at video frame rates as high as 30 frames/s. This system is based on photonics technology in which electric near-fields are applied to an electrooptic crystal plate and a sensing light beam is modulated there. The frequency of modulation is down-converted by using a photonic heterodyne of large-scale parallelism, and the spatial pattern of the electrooptic modulation is detected with a high-speed image sensor. A digital signal processor is used to extract the frequency component of interest and to animate it on the display screen. As examples, we present live pictures of electric field pattern data acquired by the LEI system in a real-time manner.Index Terms-Electromagnetic field imaging, electrooptic measurement, large-scale parallelism, photonic heterodyne, real-time imaging.

“…Moreover, the size of UWB antennae make them incompatible with measurements inside equipments of reduced size. The recent development of pigtailed electrooptic (EO) sensors [2] could constitute a competitive alternative to antennae as they can bring solutions to the above-mentioned drawbacks. However, EO probes that were developed up to now suffer from the drift of their response with the temperature.…”

We present pigtailed electro-optic probes that allow a simultaneous measurement of high frequency electric fields and temperature using a unique laser probe beam. This has been achieved by the development of a novel probe design associated with a fully automated servo-controlled optical bench, initially developed to stabilize the electric field sensor response. The developed electro-optic probes present a stable response in outdoors conditions over time duration exceeding 1 hour, a frequency bandwidth from kHz to tens of GHz with a sensitivity of 0.7 V.m -1 .Hz -1/2 and a temperature accuracy of 40 mK.
