Application of Electromagnetic Charge Effect for Development of Optical Sensors

Abstract

During our studies it was found that during interaction of electromagnetic field with matter, the irradiated body begins to generate an alternating electrical signal. These results are grouped under the name Electromagnetic echo effect (EMEE). The measured signal is a function of the state of the body. In the present work, some of the new types of optical sensors created on that basis are discussed. Such sensors are for control of: fog parameters, fog emergence, impurity emergence in fog, processes at the threshold of laser ablation and phase transitions in liquid crystals. Also, a scanning system has been developed for visualization of irregularities on surfaces.
