Abstract

The paper discusses the fundamental constitution of the later-atmosphere communication, which uses the semiconductor lasers as light sources and the photoelectric sensors as receiving devices. It makes a deep going study to the key technique -- that the problem of receiving the large-scale signals. To resolve this problem, the system uses plane mirrors, and hollow awls as the optical receiving aerial, at the same time; it makes an extensive-area photoelectric sensor whose diameter is 50 mm with 150 multiple photodiodes. The article also discusses and analyzes the technical difficulties in detail, which come from the extensive-area photoelectric receiving. The anti-light saturation of the extenive-area photoelectric sensors, the interference of background luminance and the problem of answering time. The system is successfully used in the practical engineering fields.
