Abstract
Methods and systems for measuring the temperature of a sample can include the use of one or more illumination sources and a sample containing thermochromic material. One or more detectors are operable to detect two or more signals indicative of a component of an illumination facilitated by the illumination source(s) and scattered at two or more angles with respect to the sample containing the thermochromic material, wherein the signals are converted to a temperature.

A system for measuring the temperature of a sample, comprising:
- at least one illumination source;
- a sample containing thermochromic material comprising thermochromic liquid crystal (TLC) particles;
- and
- at least one detector operable to detect at least two signals indicative of a component of an illumination facilitated by the at least one illumination source and scattered at at least two angles with respect to the sample containing the thermochromic material, wherein the at least two signals are converted to a temperature that is used to detect a temperature shift in the TLC particles using a single wavelength and the at least two angles and wherein the single wavelength is selected for optimization of the properties of the system for measuring the temperature of the sample.

- and
- using the temperature converted from the at least two signals to detect a temperature shift in the TLC particles using a single wavelength and the at least two angles and wherein the single wavelength is selected for optimization properties of a system for implementing the method for measuring the temperature of the sample.
A computer-program product for measuring the temperature of a sample, the computer-program product comprising a non-transitory tangible computer-readable medium having computer-readable instructions thereon, the computer-readable instructions being executable by a processor to cause the processor to perform:
- illuminating with at least one illumination source, a sample containing thermochromic material comprising thermochromic liquid crystal (TLC) particles;
- detecting with at least one detector, at least two signals indicative of a component of an illumination facilitated by the at least one illumination source and scattered at at least two angles with respect to the sample containing the thermochromic material;
- and
- converting the at least two signals to a temperature;
- using the temperature converted from the at least two signals to detect a temperature shift in the TLC particles using a single wavelength and the at least two angles, wherein the single wavelength is selected for optimization of the properties of the system for measuring the temperature of the sample.
