Title: Optical transmission method of signal by self-excited heterodyne method and transmission system accompanying transformation matrix
Inventor: RUNE OOFURE
IPC: H04B10/142
Filed: 1990-06-01
Abstract: PURPOSE: To simplify circuit constitution by obtaining the carrying frequency of the transition of transmitting frequency by the use of modulation frequency completely different from the carrying frequency to be selected in accordance with a receiver and transmitting a transmitting frequency signal to the same optical link. CONSTITUTION: Modulation frequency F1 is selected for a subscribed equipment to which the frequency F1 is allocated and frequency FN is selected for a subscriber equipment to which the frequency FN is allocated. In the case of requiring the sending of the same signal to all N subscribed equipments, N modulation frequency bands F1 to Fn are selected and a beam generated from a single frequency laser 1 controlled by a feeding circuit is passed through an acoustic-optical modulator 20 excited by a frequency generator 21. The incident beam is divided into two beams on the output terminal of the modulator 20, the refracted beam is transmitted along a route A and the unrefracted beam is transmitted along a route B.  The unrefracted beam has the frequency equal to the frequency adding/subtracting the modulation frequency (exciting frequency of the modulator 20) to/from the frequency of the incident beam. Consequently the circuit constitution is simplified.

Filed: 1990-05-31
Abstract: PURPOSE:To independently correct the DC component transmission rate by providing a switch circuit which normally selects the output of one of first and second circuits and selects that of the other at the time of arrival of a clamp pulse. CONSTITUTION:A first circuit 2 outputs an inputted luminance signal as it is, and a second circuit 3 is coupled to the inputted luminance signal by a parallel circuit consisting of a resistance R2 and a capacitor C1. A switch circuit 4 normally selects the output of one of first and second circuits 2 and 3 and selects that of the other at the time of arrival of the clamp pulse. The waveform of the inputted luminance signal is not deformed but only the pedestal level is changed by switching between the output signal of the first circuit 2 and that of the second circuit 3 in the pedestal period to change the DC component transmission rate. Thus, the DC component transmission rate is independently corrected.
