| Abstract: | During the exploration of the underground medium structure,the gradiometer as well as its new deployment styles for various applications has become an important research topic of world concern.This paper describes various kinds of gradiometers based on tor-sion balance and difference algorithm and deals with the principle of each instrument.In addition,the absolute gradiometers based on the laser and atom interference are also described.In the last part of this paper,the design of the measurement light path is presented. The results obtained by the authors can serve as the technologic reference for developing gradiometer. |
