Abstract

The invention provides an optical electric field sensor packaging device and packaging method for a high-humidity environment. The packaging device comprises two optical fiber flanges, a tube shell body and a tube shell cover. The tube shell body is provided with an accommodating cavity for accommodating a sensor wafer. The tube shell cover is used for covering the tube shell body. Two opposite side walls of the tube shell body are respectively provided with through holes matched with the two optical fiber flanges. The optical fiber flanges, the tube shell body and the tube shell cover are all made of a material which is weak in water absorption and water permeability. The optical electric field sensor packaging structure is improved, a tube shell sealing sensor is made of a material with weak water absorption and water permeability, and hydrophobic treatment is carried out on the outer layer, so that the measurement precision of the sensor is basically not influenced by environmental humidity, and the application scene of the optical electric field sensor is widened.

Description

technical field [0001] The invention belongs to the technical field of electric field measurement, and in particular relates to an optical electric field sensor packaging device and a packaging method used in a high-humidity environment. Background technique [0002] The optical electric field sensor has attracted many scholars' research because of its wide frequency band, small size, and convenient installation. The development of science and technology has higher and higher requirements for the accuracy of electric field measurement. However, when the sensor is used for outdoor measurement, the ambient humidity will affect the measurement accuracy of the sensor. [0003] The usual way to improve the applicability of optical electric field sensors in high-humidity environments is to improve the packaging structure of the sensor and improve the sealing degree of the sensor package. Considering the thermal expansion of the optical electric field sensor pigtail will produce ...
