The invention discloses a measuring method and device for inverting optical properties of aerosol based on tetrapolyoxygen absorption. The method comprises the steps of: establishing an atmospheric radiation transmission model; analyzing and calculating the sensitivity of O4 batter post concentration to aerosol optical parameters; performing parameterization expression on inversion key parametersto obtain aerosol optical parameters; substituting different atmospheric aerosol states into the atmospheric radiation transmission model, simulating O4 absorption intensity, and establishing a lookuptable; building a ground-based passive differential absorption optical system capable of performing all-sky observation; obtaining actual scattered spectrum of all-sky different angles in the atmosphere, performing passive differential absorption spectrum fitting, and measuring the actual O4 absorption intensity; and performing least square fitting on the actual measurement result and the simulation result, and performing
