Three-dimensional laser scanner is adopted to protect and study on Lianyungang City General Cliff petroglyph by institute of key cultural relics protection. Through the high-precision scanning by Surphaser for important locations, including the faces, crops, chessboard, milky way, meridian, society, the Sun and so on, three-dimensional dates of 22 stations were obtained. After splicing these points cloud by Leica Cyclone, AVI video was generated on the basis of development path of camera, and a complete animation video was obtained by video editing software at last. The results show that three-dimensional laser scanner can be used for fast, accurate completion of rock digital and the effect on the conservation and research of cultural relics protection is very favorable.

This paper presents a novel RFID antenna which makes solar cell and tag antenna combine as an integrated unit. The solar cell is used as a parasitic element in a tag antenna. The original feature of a solar cell (DC current generation) remains, and the solar cell which can supply the energy to activate the IC is now used as a parasitic patch at the same time. Besides a general description of solar cell antenna, the size and the simulated results of the antenna are also shown.
