Two essentially different mathematical approaches to define coherent states of finite-dimensional Hilbert spaces are analyzed.Physical realizations of the s0-called quantum scissors to generate the finite-dimensional states via optical truncation are discussed including the linear-0ptical scheme of Pegg, Phillips and Barnett [Phys.Rev. Lett.81, 1604 (1998)] and nonlinear one of Leonski and Tanas [Phys.Rev. A49, R20 (1994)].Distinct properties of the generated states are studied by applying adiscrete Wigner function.
