We describe the measurements of infrared detection in granular and epitaxial films of YBa2Cu3O7−δ. The experimental frequency response measurements stated that the response voltage of detector for epitaxial film decreased much more rapidly than that for granular film. Different relationship of infrared response and bias current for detectors from two types of films has been demonstrated. We attribute the descrapency to the characters of detectors associated with different types of film structures.
