The distinction between the bolometric and non-bolometric responses of high T-c TI- and Bi- oxide superconducting thin films is presented by comparison of the characteristics of the responses at different temperatures and chopping frequencies. The bolometric optical response of the films is proportional to the dR/dT of the films; experimentally the peak optical response decreases as the chopping frequency of the radiation is increased. The non-bolometric response is not proportional to the WdT of the films and the peak microwave response was found to be almost independent of the chopping frequency.
