The design, alignment, calibration, and field deployment of a solid-state lightning detector is described. The primary sensing component of the detector is a potassium dihydrogen phosphate (KDP) electro-optic crystal that is attached in series to a fiat plate aluminum antenna; the antenna is exposed to the ambient thundercloud electric field. A semiconductor laser diode (2 = 685 nm), polarizing optics, and the crystal are arranged in a Pockels cell configuration.Lightning-caused electric field changes are related to small changes in the transmission of laser light through the optical cell. Several hundred lightning electric field change excursions were recorded during five thunderstorms that occurred in the summer of 1998 at the NASA Marshall Space Flight Center (MSFC) in northern Alabama.

“…Ground-referenced meters are normally used to measure the E-field strength on grounded conducting surfaces and base their working principle on the measurement of charge or current on a sensing electrode that is ground referenced. Electro-optic field meters based on the Pockels effect [30] and not requiring a ground reference are also used as free-body meters with a typical application being the investigation of radio frequency E-field distributions [31]. The probe is mechanically separated from the rest of the instrument and linked to it by an optical fiber.…”

In this paper, we investigate the exploitation of nonlinear behavior in ferroelectric (FE) materials in the realization of innovative transducers for detecting weak and low-frequency electric fields (E-fields). Specifically, we describe a nonlinear dynamical system based on FE capacitors coupled into a unidirectional ring circuit which, under the appropriate operating conditions, exhibits an oscillating regime of behavior in the response variable (the electric polarization). In this device, a weak target E-field induces a perturbation of the polarization of the FE material; in turn, the target signal can be detected and quantified via its effect on the coupled system response. Hence, the device entails the synergetic use of bistable FE materials, micromachining technologies that allow for addressing charge density amplification, and novel sensing strategies based on coupling nonlinear elemental cells. The "charge collector" strategy has been employed to detect the target field. An experimental characterization of the sensing device, including three cells (each cell corresponds to an FE capacitor) coupled in a ring configuration, is presented as a function of the charge collector configuration.Index Terms-Ferroelectric (FE) capacitor, hysteresis, nonlinear dynamical system, quartic bistable potential, quasi-static electric field (E-field) sensors, Sawyer-Tower (ST) circuit.

“…They are used as materials for wave front amplification, conjugation, and self-conjugation systems, adaptive holographic interferometers, spatial-frequency filters, photodetectors, and other dynamic holography devices [1-4, 7, 8], and also for bulk and surface acoustic wave devices (filters, delay lines, and others) [9] and electric/magnetic field sensors [10,11]. Bi 2 O 3 -based phases isostructural with γ -Bi 2 O 3 (mineral sillenite) are called sillenites [12].…”

The main processes for preparing bulk single crystals and films of photorefractive and piezoelectric Bi 12 M x O 20 ± δ (M = Group II-VIII elements) sillenite compounds are considered. Experimental data are summarized on the crystal growth of Bi 12 M x O 20 ± δ from the melt and under hydrothermal conditions, and the key morphological features of sillenites are analyzed. Various types of macroscopic growth defects in sillenite-type crystals are described, and their origin is discussed. The compositions of second-phase inclusions in undoped and doped (Group I-VIII elements) Bi 12 SiO 20 , Bi 12 GeO 20 , and Bi 12 TiO 20 single crystals are presented, and the main physicochemical properties of various Bi 12 M x O 20 ± δ crystals are summarized.
