Abstract: A method of determining a temperature of an element in a scene includes providing a set of targets each characterized by a target temperature and measuring pixel output values for pixels in a detector array for the targets in the set of targets. Measuring pixel output values is performed at a plurality of detector temperatures. The method also includes mapping each pixel output value to one of a plurality of constant values, each of the plurality of constant values being associated with one of the target temperatures, assembling a scene temperature profile using the mapped pixel output values, and obtaining an image of the scene including the element, wherein the element is associated with a pixel of the detector array. The method further includes determining a pixel value associated with the element and computing the temperature of the element using the scene temperature profile.
