A wireless atmospheric site-to-site full-duplex (i.e., simultaneous transmit
and
receive) laser communication system, typically for wideband (high-speed) data,
voice, and/or video transmission. The system includes at least one laser communication
transceiver each having an electro-optical transmitter that includes a laser source
for generating laser light to be transmitted site-to-site and at high speed, an
electro-optical receiver that includes a baffle assembly for receiving light directly
onto a detector, without an intermediate field stop and re-imaging relay optics
to reject off-axis light sources. Wideband data are transmitted and received through
the atmosphere by the electro-optical transmitter and the electro-optical receiver.
The data to be transmitted through each laser communication transceiver is inputted
through a fiber-optic receiver and outputted by a fiber-optic transmitter. Outgoing
laser light is generated by the laser source after it is triggered by an inputted
signal from the fiber-optic receiver.
