OPERATIONAL RANGE DESIGNATION AND ENHANCEMENT IN OPTICAL READOUT OF TEMPERATURE

摘要

Methods for addressing a designated temperature operational range in a measurement that uses an optical readout of temperature and for enhancing that range are disclosed. The range is enhanced through providing at least one active detector with a periodic response, operative to provide a detector temperature through an electric field-dependent optical readout, and performing at least two measurements of the detector temperature to obtain a non-degenerate reading of an object temperature. The at least two measurements may include three same wavelength/different electric field measurements or two same electric field/different wavelength measurements. The operational range is addressed by using at least one pixel and an associated dummy detector, identifying a center temperature T_center of an object temperature range, calculating a pixel temperature T* correlated with T_center, calculating an electric field E*, which, once applied to the dummy detector, yields a light intensity reading that is half a maximal intensity value, and optically reading each pixel temperature.
