Claims

[Scope of utility model registration request]

In an antenna alignment device that determines the reference angle of the direction of the opposing transmitting antenna and the receiving antenna on the side of the specimen, there is provided a waveguide connected to the transmitting antenna, a photocoupler and a laser provided on the narrow side of the waveguide. An optical cable connects an oscillator, a laser output port of the laser oscillator, and the photocoupler, one end of which is connected to the photocoupler, and the other end that serves as the output end of the laser beam. It is characterized by comprising an optical fiber provided inside the waveguide so as to output an output parallel to the guiding direction, and an electrical adjustment screw provided in the waveguide in a direction perpendicular to the axial direction of the waveguide. antenna alignment device.
