Double-blind frequency-resolved optical gating (DFROG) is an advanced technique used in the field of ultrafast optics to characterize the temporal properties of short laser pulses. It is an extension of the original frequency-resolved optical gating (FROG) method, which is used to measure the electric field of a pulse by using the properties of nonlinear optics.
