    "abstract": "We show how two level atoms can be used to determine the local time dependent\nspectrum. The method is applied to a one dimensional cavity. The spectrum\nobtained is compared with the mode spectrum determined using spatially filtered\nsecond order correlation functions. The spectra obtained using two level atoms\ngive identical results with the mode spectrum. One benefit of the method is\nthat only one time averages are needed. It is also more closely related to a\nrealistic measurement scheme than any other definition of a time dependent\nspectrum.",
