Abstract: PURPOSE: A signal detecting circuit of an infrared ray sensor and a collecting method thereof are provided to minimize a non-uniformity among pixels, to maximize a circuit dynamic range of a temperature of a micro-bolometer FPA(Focal Plane Array), and to obtain detecting characteristics by improving an amplification factor. CONSTITUTION: A signal detecting circuit of an infrared ray sensor comprises a cell array(120), a level generator(140), a resistance non-uniformity correction circuits(150) of N, a resistance non-uniformity correction circuits(125) of M, a controller(115), and an integrator. Bolometer outputting a signal current by detecting infrared rays is arranged in the cell array. The level generator outputs a plurality of bias voltages corresponding to a plurality of bias levels. The resistance non-uniformity correction circuits of N are arranged in a column direction of the cell array, thereby supplying the bias voltages different to each other to the each bolometer. The resistance non-uniformity correction circuits of M are arranged in a row direction of the cell array, thereby supplying the bias voltages different to each other to the each bolometer. The controller sets bias voltage levels of the each resistance non-uniformity correction circuits so that the resistance non-uniformity of the cell array is corrected. The integrator integrates the signal current outputted from the cell array.
