Abstract

Методът и устройството намират приложение в далекосъобщителната техника. По метода от предавателната към приемателната страна се насочват най-малко два кохерентно модулирани снопа лъчи, намиращи се на излъчващо междуосово разстояние, най-малко 200 мм и 100 така, че се пресичат върху приемателната страна. Общата интензивност на пресичащите се снопове лъчи се детектира и се въвежда информацията от получаващия се при детектирането сигнал. В устройството върху предавателната страна към един модулатор (м) са съединени най-малко два предавателя (а1 и а2) с устройства за формиране на снопове. Те са разположени помежду си на разстояние, най-малко 200 мм и 100 ( означава д ължината на използваната електромагнитна вълна). 18 претенции, 1 фигураThe method and device find application in telecommunications technology. In the method, at least two coherently modulated beams are directed from the transmitting side to the receiving side, located at an radiating center distance of at least 200 mm and 100 mm so that they intersect on the receiving side. The total intensity of the intersecting beams is detected and the information from the detected signal is entered. In the device, on the transmission side, at least two transmitters (a1 and a2) with beamforming devices are connected to one modulator (m). They are located between each other at a distance of at least 200 mm and 100 (means the length of the electromagnetic wave used). 18 claims, 1 figure
