A principle of operation for high temperature superconducting infrared detector with grain boundary structure was proposed, in which both bolometric and optically non-equilibrium effects coexist. Responsivities of the detector with the two effects were calculated. The YBa2Cu3O7-xinfrared detector was prepared. With the chopping frequency of 10 Hz, its responsivity, detectivity and noise equivalent power were measured to be 3.0×103V/W, 1.5×109cmHz1/2/W and 4.2×10-12W/Hz1/2, respectively. The frequency characteristic of the infrared detector was illustrated and discussed.
