SPACE OPTICAL COMMUNICATION LINE BETWEEN TWO OBJECTS Russian patent published in 1998 - IPC

FIELD: space optical communication. SUBSTANCE: invention solves problem of provision for continuous optical communication between two objects one of which or both rotate about their centers of masses with simultaneous increase of reliability and maintenance of functional flexibility of space optical communication line. Space optical communication line has receiving-transmitting equipment located on each object. Terminal optical unit of optical equipment is mounted on support and is composed of rotary and immobile units. Rotary unit is mounted for turn of terminal optical unit about lateral axis and for turn of rotary unit relative to immobile unit made fast with location surface to body of object. Second set of optical equipment with terminal optical unit is brought into space optical communication line. Location surface of rotary units of first and second sets of equipment on one object face each other. Axes of turn of terminal optical units of antennas cross axes of turn of rotary units. Axes of turn of rotary units of supports of first and second sets of equipment on object also cross. Range of overlapping of turn angle of rotary units with reference to immobile units is determined by dependence. EFFECT: increased reliability and maintenance of functional flexibility of space optical communication line. 1 cl, 6 dwg
