IPC: G02B26/10
Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a scanning optical device capable of exactly detecting the scanning position of a plotting light beam, applicable even when a plotting objective surface is a plane and without being affected by the error of a shape of mirror even by providing the mirror for separating the optical path of a monitor light beam from the optical path of a plotting light beam. SOLUTION: A monitor light beam L2 and a plotting light beam L1 are made incident on a polygon mirror 40 at different angles so that they are separated in the subscanning direction after transmitting through a fθ lens and the convergent degree of the monitor beam L2 is made larger than that of the plotting light beam L1. Consequently, the monitor light beam L2 is set so as to be converged just before a plotting objective surface 60 and a transmission scale 70 is arranged by making it coincident with the convergent position.

Abstract: PROBLEM TO BE SOLVED: To obtain an excellent reception state without using a plurality of antenna by shifting the phase of an output signal depending on a reception state, revising a radiation pattern and emitting a radio wave from a corresponding radiation face of an array antenna. SOLUTION: In the case of transmission, an input signal from an interface 1 is given to a phase shifter group 5 via a modulator 2, a transmitter 3 and a branching filter 4. The phase of the signal is shifted in the group 5 according to a phase control signal from a ROM 15 and a radio wave is emitted from a corresponding radiation face of an array antenna 6. In the case of reception, a reception radio wave is given to an IF amplifier 8 via the array antenna 6, the phase shifter group 5, the branching filter 4 and a receiver 7. The signal is outputted to the interface circuit 1 via a demodulator 10 and a BER measurement circuit 11 counts a bit error rate BER. A control circuit 13 compares the BER with a standard value and sends information of revision of a radiation pattern to the phase shifter group 5 via the ROM 15.  Thus, an excellent reception state is obtained without using a plurality of antennas.
