Abstract:
     The present invention is the method for vertically transmitting azimuth angle to ensure horizontal synchronism between two, one upper and one lower, equipments without mechanical connection. Light from light source is first converted in a polarizer into linear polarized light, which is modulated in a magnetooptical modulator, then passes through a analyzer and converted into electrical signal in a photoelectronic receiver. When the frequency selecting amplifier detects no signal with frequency equal to the said modulation frequency, the azimuth angle of the analyzer is equal to the azimuth angle of the polarizer so completing the vertical transmission of azimuth angle.
