This paper shows that dissipative dynamical systems with constant Jacobian allow one to discover the numerical values of physical parameters under which the system is operating. This is done by performing measurements on self-similar (fractal) structures of the phase-space. Parameter recovery is illustrated explicitly for the Ikeda laser ring-cavity map and the Hénon map. The first model involves transcendental equations of motion that can be solved only numerically. Analytical results are obtained for the second model. In both cases the macroscopic dissipation rate of the dynamical system is recovered from the speed at which fractal "fingers" making up basins of attraction accumulate towards basin boundaries.
