Improved measurement accuracy of the quadrant detector through improvement of linearity index
Song Cui and Yeng Chai Soh
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 ...
