Theoretical analysis of 2D acceleration laser sensor and several design parameters

Having adopted several sets of new technology and techniques, we have developed a new type of laser angle sensor that can be used to measure two-dimensional (2D) angle of moving target. On this basis, a new design for 2D acceleration laser sensor has been advanced. The optics-type sensor can be used to measure 2D acceleration of motion object, and it has high sensitivity, high precision and longer measuring range. Under these design parameters that are given in this paper, the measuring range will achieve 177 g, while its sensitivity is 13.5 s². The experimental results show that the measuring error is not greater than 0.1 g. In this paper, several design parameters and measuring results for 2D acceleration laser sensor are given.
