PROBLEM TO BE SOLVED: To provide a light directional transmission/reception equipment with which an image of high quality can be obtained, in an equipment for the directional transmission and reception of modulated light waves between geostationary satellites, namely, the geostationary satellites closer to the earth through a telescope. SOLUTION: The equipment for the directional transmission and reception of modulated light waves between geostationary satellites, namely, the geostationary satellites closer to the earth through a telescope is provided with a housing 50 composed of a plate 34 having a honeycomb structure surrounded with a thin layer having low thermal expansion characteristics and an inclined reflecting telescope constituted symmetrically and installed on a yoke 52 attached so as to be rotatable on a ring 54. In this case, the inclined reflecting telescope has no image pickup error and the bidirectional simultaneous transmission/reception of the light waves possible. |
