The problem of measuring interferometrically both the mass density and the electron concentration in an ionized gas requires interferograms at 2 different wavelengths. Transient ionized gases can be examined by the method of streak interferometry. By inserting a dichroic mirror-divider and duplicate optical trains with appropriate filters, the basic treak interferometer can be modified to produce 2, simultaneous, streak interferograms at selected wavelengths.
