LASER COMMUNICATION SYSTEM COMPRISING LASER COMMUNICATION APPARATUS AND METHOD FOR SETTING ROUTE, AND LASER COMMUNICATION MESH NETWORK SYSTEM

摘要

PURPOSE: A laser communication system, path setup method, and laser communication mesh network system are provided to acquire reliability for transmitting data selectively using good communication environments. CONSTITUTION: A control unit(150) measures a communication state with other laser communication apparatus(200) using a direct communication path. When A lase communication system is unable to communicate with other lase communication apparatuses using the direct communication path, a control unit sets the direction of a light emitting unit(110) and a light reception unit(120) according to the control of a direction control unit(130). A laser communication apparatus(100) faces to a relay mirror according to the control of the direction control unit. The control unit executes laser communication with other laser communication apparatus using the relay mirror.
