A method for contactlessly establishing a temperature of a surface includes determining the temperature measurement values of the plurality of measurement pixels. The method further includes correcting the temperature measurement values by using in each case a pixel-associated temperature drift component. The method further includes at least temporarily suppressing an incidence of infrared radiation onto the infrared detector array using the closure mechanism of the infrared measurement system while temperature measurement values are being determined. The method further includes determining the temperature drift components using the temperature measurement values.

A system and method for calibrating an imaging system includes a shutter that is moveable in to the optical path of the imaging system to generate an image of the shutter surface, which is flat and uniform. The shutter can be moved in and out of the optical path between first and second positions. The shutter is heated while in the second position and then returned to the first position. Data sets generated at two different temperatures enable the image generated by the imaging system in normal use to be to be adjusted for responsivity and variation in DC offset of the specific pixel array.

A shield plate that is used for non-contact measurement of a temperature of a measurement target is provided. The shield plate includes a base of which a temperature is adjustable. The base includes a central shield portion that is formed in the shield plate, an opening that is formed around the central shield portion, and a blackbody surface that is formed on one surface of the base to include a portion opposite to the opening with the central shield portion interposed therebetween and to radiate infrared rays.

A calibration system for a passive millimeter-wave (PMMW) camera. The calibration system includes a thermal calibrator having a first thermally conducting body, a second thermally conducting body, a first black body target mounted to a front surface of the first conducting body, a second black body target mounted to a front surface of the second conducting body, and a thermo-electric (TE) cooling device having a hot side and a cold side. The hot side of the TE cooling device is thermally attached to the first conducting body and the cold side of the TE cooling device is thermally attached to the second conducting body.
