LASER COMMUNICATION DEVICE

摘要

A portable laser communication transceiver for transmitting and receiving information imposed on laser beams. A communication signal is imposed on a laser beam having a divergence of between 1 degree and 4 degrees. The beam (27) is directed by an operator, sighting through a telescopic viewing device (26), at a distant transceiver which collects light in the laser beam and extracts the communication signal. In preferred embodiments, the transceivers are handheld and each comprises a microphone (22) and earphone (20) allowing operators to talk with each other. Digital information can also be transmitted from personal computers and other electronic information equipment at the location of each operator. In a preferred embodiment useful for military and surveying applications, a GPS, a compass, and a laser ranging system is provided. This enables the operator to sight through a binocular to a target and determine its position in longitude, latitude and elevation. Target position information can then be transmitted to a distant transceiver which in this case could be a base transceiver.
