ELECTROMAGNETIC WAVE MEASUREMENT PROBE, ELECTROMAGNETIC WAVE MEASUREMENT SYSTEM, AND BUNDLED OPTICAL FIBER

摘要

[Summary][Problem] To provide an electromagnetic wave measurement probe that is able to measure the spatial distribution characteristics of an electromagnetic wave with a differential measurement.[Solving Means] An electromagnetic wave measurement probe of the present invention includes a first measurement unit having a sensor structure that includes an electro-optic crystal that exhibits an electro-optic effect, an optical fiber that is provided on the root side of the electro-optic crystal and is configured to transmit an optical signal, and a reflection unit that is provided on the tip side of the electro-optic crystal and is configured to reflect the optical signal, and a second measurement unit having the sensor structure, and in first and second directions perpendicular to the axis direction of the optical fiber, the size of the electro-optic crystal is set to 1/2 or less of the wavelength of the measurement target electromagnetic wave, so that the electromagnetic wave may be measured with high accuracy.
