Black body spectroscopy has been neglected by experimentalists for fifty years. We propose to apply interferometric methods to black bodies with the prospect of getting temperature values based on frequency standards in the range from 90 K and upwards. When applied to higher temperature sources, the same methods could tell us new things about photons.
