Free space optical communication is the bidirectional transmission technology that puts to use the laser beam as a carrier in space. Free space optical communication is generally used in the severe space environment. It is the mainly problem that the narrow beam of laser beam is high-precision aimed. and it is became very important that the technology of ATP is researched. Performance of the ATP system directly affects the performance of the quality of the free space optical communication. So research of the ATP is the key technology in FSO and this technology is discussed and analysed in the article. 2012 Chinese Assoc of Automati.

A small size Free Space Optical Communication System is introduced including the hardware and the hardware specified physical layer protocol. In detail the rapid synchronization method to reduce the handshake bandwidth requirement is demonstrated. The hardware of the system includes the laser driver system the signal amplifying and shaping system the data interface system. The hardware specified physical layer protocol is used to interface the outer data serialize and deserialize the data stream check transmission errors and schedule the data transmission. The overall system is a FIFO-like system and the user can use it as if he's operating a FIFO. The system is designed mainly for terrestrial FSO link whose signal channel is the atmosphere. Due to the complex composition and activity of the atmosphere this signal channel brings in great influence on the transmitting laser in it for example the absorption and scattering of the atmosphere molecules and aerosols the scintillation of received laser power caused by the turbulence of the atmosphere all of which results in a much higher Bit Error Rate (BER) of the communication system than wired communication systems leading to frequent resynchronization. In our system the sampling clock is generated locally using multi-phase sampling technique rather than PLLbased clock recovery which helps to rapid synchronization. 2012 IEEE.

The reconnaissance satellite communication satellite and navigation satellite used in the military applications have played more and more important role in the advanced technique wars and already become the significant support and aid system for military actions. With the development of all kinds of satellites anti-satellite laser weapons emerge as the times require. The experiments and analyses of laser disturbing CCD (charge coupled detector) in near ground have been studied by many research groups but their results are not suitable to the case that using laser disturbs the satellite-based detector. Because the distance between the satellite-based detector and the ground is very large it is difficult to damage it directly. However the optical receive system of satellite detector has large optical gain so laser disturbing satellite detector is possible. In order to determine its feasibility the theoretical analyses and experimental study are carried out in the paper. Firstly the influence factors of laser disturbing satellite detector are analyzed in detail which including laser power density on the surface of the detector after long distance transmission and laser power density threshold for disturbing etc. These factors are not only induced by the satellite orbit but dependence on the following parameters: laser average power in the ground laser beam quality tracing and aiming precision and atmospheric transmission. A calculation model is developed by considering all factors which then the power density entering into the detector can be calculated. Secondly the laser disturbing experiment is performed by using LD (laser diode) with the wavelength 808 nm disturbing CCD 5 kilometer away which the disturbing threshold value is obtained as 3.5510-4mW/cm2 that coincides with other researcher's results. Finally using the theoretical model the energy density of laser on the photosensitive surface of MSTI-3 satellite detector is estimated as about 100mW/cm2 which is largely exceed the disturbing threshold and therefore verify the feasibility of using this kind of laser disturbing the satellite-based detector. According to the results. using the similar laser power density absolutely saturate the requirements to laser disturbing satellite-based detector. If considering the peak power of pulsed laser even decrease laser average power it is also possible to damage the detector. This result will provide the reliable evidences to evaluate the effect of laser disturbing satellite-based detector. 2009 SPIE.

As a result of comparative study on human visual and Free Space Optical (FSO) communication a new concept of satellites laser interconnect was proposed based on human bionics. For the laser link is difficult to set up directly a new concept was given out based on the three processes of human visual capturing the objectives: voice assisting to guide eyes' wide Field Of View (FOV) cursory capturing and eyes' foveal FOV high-resolution imaging. Three similar processes were introduced to spaceborne laser interconnect which were radio assisting to guide beacons laser wide FOV capturing and communication laser narrow FOV capturing so that the difficulty of setting up the optical communication link was reduced evidently. Meanwhile the antenna optical system based on the bionics was given out. Each laser terminal configured two independent optical antenna through the spaceborne storage and time-domain link switching complex topology network could be set up. The simulation system was built using Virtual Reality Toolbox the result showed that the laser terminal could search and set up communication links which took about only lOOms from capturing the beacon to setting up communication. 2009 IEEE.
