One of the quantum metrology goals is to improve precision in measurement a small optical phase introduced one mode an interferometer, i.e., sensing. In this paper, we obtain relative distribution by Luis and S\'anchez-Soto (LSS) [Phys. Rev. A $\mathbf{53}$, 495 (1996)] for several two-mode pure light states useful metrology. We show that, within numerical our calculations, Fisher information o...
