Abstract
The invention relates to a system and method for the optical calibration of the temperature of a micro-environment. The system comprises a thermochromic liquid crystal in combination with a luminophore. The steps of the method comprise providing in combination in the micro-environment at least one thermochromic liquid crystal and a luminophore, varying the temperature of the environment while irradiating the combination with light that includes light at one or more excitation wavelengths of the luminophore, and monitoring luminescence emitted by the combination while recording the temperature of the environment.
