1. A method for determining the temperature of an object without physically contacting the object, comprising: reading a spectral radiation of the object over a plurality of wavelengths to obtain a set of radiation data related to a temperature of the object; determining a known characteristic of a black body at a plurality of test temperatures; generating a set of ratios of said characteristic of said black body to said radiation data, at each one of said plurality of test temperatures; generating an array of standard deviations, with each one of said standard deviations of said array being associated with a specific one of said set of ratios; and using said set of ratios and said array of standard deviations to determine a temperature of the object.
