DEVICE AND PROCEDURE MEASURING GRAVITATIONAL FORCE Russian patent published in 2003 - IPC

FIELD: determination of gravitational acceleration. SUBSTANCE: measurement of gravitational force based on measurement of angles of turn of pendulums of double elastic system of twisting type by autocollimation method is carried out under pulse mode in following sequence: zeroing of light-sensitive region and reading resistors of charge-coupled device is executed with arrival of synchronization pulse from outside source, charge-coupled device is illuminated for short time, after this volume charges stored in elements of charge-couple device are transferred into reading registers which output voltage is converted to digital code used to compute position of image of autocollimation mark and transmitted then into computer through series interface. EFFECT: raised accuracy of dynamic range and instrument precision with simultaneous growth of frequency of reading of gravitometrical data. 5 cl, 6 dwg
