We present simple closed-form expressions for evaluating the overall and the Pancharatnam–Berry phase introduced by an optical system with either orthogonal or nonorthogonal eigenpolarizations. The formulas provide a meaningful connection with the Pancharatnam–Berry phase associated with nonclosed paths on the Poincaré sphere.
