Description

technical field [0001] The present application relates to the technical field of fluorescence intensity ratio temperature measurement, in particular to a temperature measurement method, device, temperature measurement sensor and computer-readable storage medium. Background technique [0002] The accurate measurement of temperature plays a vital role in many fields such as industrial production, electronics industry, scientific research, aerospace and national defense construction. With the rapid development of nanotechnology, fields such as microelectronics, nanophotonics, and biomedicine have put forward higher standards for temperature measurement. Traditional contact thermometers are difficult to miniaturize due to their size limitations, so it is of great significance to develop new non-contact temperature sensors with advantages such as high detection sensitivity and spatial resolution, non-invasiveness, and fast response.

Problems solved by technology

The inventors of the present application discovered during the research and practice of the fluorescence intensity ratio temperature measurement process that the existing related technologies are generally based on a single criterion for temperature sensing, and the single criterion can only provide a single temperature measurement parameter, resulting in the lack of optimization of its key parameters possible

A small number of multi-criteria work did not effectively integrate multiple criteria. In fact, the advantages of expanding the temperature measurement area and optimizing key temperature measurement parameters that can be brought about by multi-criteria have not been realized.
