The invention discloses a method for generating a cylindrical vector light beam penetrating a scattering medium, and the method comprises the following steps: S1, selecting the polarization state of incident light through rotating a polarizing film, and measuring transmission matrixes in two polarization directions; s2, constructing a new operator by using a mask, and obtaining a transmission matrix for encoding the cylindrical vector light beam; s3, combining the output light fields in the two polarization states, and performing binary polarization approximation to obtain a polarization transmission matrix; and S4, loading the conjugate polarized light field on a spatial light modulator, and performing light path playback to generate a cylindrical vector light beam through a scattering medium. According to the invention, the polarization characteristic of the cylindrical vector light beam is combined with the polarization transmission matrix, so that the research on generation of the cylindrical vector light
