One of challenges involves the difficulty of acquisition, tracking, and pointing (ATP) a concentrated beam of light arriving from another platform across the far reach of space. To meet the pointing accuracy requirement, the basic method of tracking between the terminals of optical communication systems includes the use of a beacon laser and tracking system with a quadrant detector sensor on each terminal. In some future optical communication networks, it is plausible to assume that tracking system and communication receivers will use the same sensor. In this paper, the architecture of the fine tracking assembly of the designing optical communication terminal (OCT) is described, and the fine tracking assembly sensor is modeled based on the correlation coefficient. The simulation and experiment results of the sensor show that the detecting accuracy satisfies the design demand for our developing OCT.

Bovine shank bone was divided into two groups, each group was put on a PC-controlled motorized linear drive stage which was located on the preand post-focus plane with a beam spot size of about 510 μm respectively and moved repeatedly through the focused beam. The wavelength of pulse CO2 laser was 10.64 μm, pulse repetition rate was 60 Hz. The moving speed of the stage was 20 mm/s, scan times was 6. the zone of thermal damage and crater morphology produced by pulse CO2 laser ablation were examined by light microscopy following standard histological processing. The results demonstrate that defocus irradiation condition has an important effect on ablation crater profile, crater morphology and the zone of collateral thermal damage. By selecting proper radiant exposure and focusing the beam spot not above but slightly beneath the bone surface, narrower but deeper cut with minimum collateral thermal injury can be obtained.
