This invention provides a two-dimensional measurement method for combustion field temperature. The laser frequency is tuned and stabilized at the center of an iodine molecular absorption line. The laser outputs a narrow-linewidth, single-longitudinal-mode continuous beam. This beam is split into two beams by a spectroscope. One beam travels through a reference optical path and is used to obtain the instrument function of a VIPA-based spectrometer. The other beam, acting as excitation light, is incident on the combustion field, where it interacts with the combustion gas to generate a scattered signal. A light collection system collects and filters the scattered signal to produce filtered Rayleigh-Brillouin scattering (FRBS), which is then transmitted via optical fiber to a spectrometer and CCD for spectral resolution and signal acquisition. A scanning system completes a two-dimensional profile scan of the combustion field. Using the FRBS theoretical model, the collected FRBS spectral lines are used to retrieve the temperature, achieving two-dimensional measurement of the combustion field temperature. This invention provides a method for retrieval of gas temperature based on FRBS in high-temperature environments with strong Mie scattering or background light, adapting to diverse environments and needs, offering greater flexibility.
