摘要：

This paper presents a set of formulae for estimating the beam position projected on a quadrant detector (QD). Our new formulae are designed through a systematic procedure to improve the measurement accuracy of the QD. It can be applied to different beam profiles. It is shown in simulations that our new formulae have achieved a much better measurement accuracy. It is also shown through experimental study that our approach is robust and able to achieve very good performance in practice.
