Title:
METHOD AND DEVICE FOR CALIBRATING DEVIATION FROM PREFERRED POSITION OF RECEPTION BEAM IN TERMINAL
Document Type and Number:
Japanese Patent JP2000357995
Kind Code:
A
Abstract:
To realize a method for calibrating deviations from a preferred position of reception beam in a terminal.
The reception beam arrives at the receiving sensor of the terminal and a pickup beam arrives at the pickup sensor of the terminal. The detection range of the latter is wider than that of the former. A part of a transmission beam radiated to the terminal of an opposite side by the terminal is guided onto a reflecting surface as an incident beam and is reflected as an output beam. A part of the output beam is respectively guided to both sensors. Measurement is at least nearly simultaneously executed in both sensors. The measured results are compared for deciding the deviation from the preferred position of the reception beam.
