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.

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.
