Ultrasensitive measurement of angular rotations via a Hermite-Gaussian pointer
文献摘要：
Exploring high sensitivity on the measurement of angular rotations is an outstanding challenge in optics and metrology.In this work,we employ the mn-order Hermite-Gaussian(HG)beam in the weak measurement scheme with an angular rotation interaction,where the rotation information is taken by another HG mode state completely after the post-selection.By taking a projective measurement on the final light beam,the precision of angular rotation is improved by a factor of 2mn+m+n.For verification,we perform an optical experiment where the minimum detectable angular rotation improves √15-fold with HG55 mode over that of HG11 mode,and achieves a sub-microradian scale of the measurement precision.Our theoretical framework and experimental results not only provide a more practical and convenient scheme for ultrasensitive measurement of angular ro-tations but also contribute to a wide range of applications in quantum metrology.
