Abstract A new method of measuring falling object posture is presented in order to solve the deflection of absolute gravimeter falling object.The method uses a single laser triangulation principle to analyze the relationship between optical parameters, and the selection of components and installation of structure are based on the parameter values.The result shows that the distance can reach micron level resolution in the short distance measurement (1-10 mm).
Key words :
absolute gravimeter
falling object posture
single laser triangulation measurement
