摘要：A transceiver for a through-air optical communications system and the relatedmethod for transmitting signals through air by utilizing coherent light beams. Thetransceiver according to the invention comprises a receiving reflecting surface to
properly reflect the coherent light received from another transceiver, said receivesurface defining an outer edge. The transceiver is characterized by further comprising asingle aperture in the shape of an annulus to pass the coherent light to be transmitted,said aperture substantially extending close to the outer edge of the receiving surface.Conveniently the annulus-shaped aperture is formed in the same main disk in which thereceive reflecting surface is realized. The problem of scintillation and alignment betweenreceiving and transmitting parts of the transceiver is reduced.
