Abstract

PURPOSE:To make it possible to send many different volumes of information by arraying several LEDs at narrow intervals and by sending photo signals from respective LEDs, superposed upon the same light flux, toward the space. CONSTITUTION:On the focus of reflecting mirror 1, several LEDs 2 are arrayed at narrow intervals and radiator 3 of them is directed against reflecting mirror 1 to reflect 1 infrared rays. Then, a photo signal from each LED2 is superposed upon the same light flux and sent out to the sapce. Thus, a large quantity of infrared rays are superposed and sent out by a single optical system, thereby making it possible to send many different volumes of information.
