Abstract

The invention provides a flame light field probe pan-scale analysis method based on a micro-lens array. The flame light field probe pan-scale analysis method comprises high temperature dispersion dielectric optical radiation modeling, high temperature dispersion dielectric radiation characteristic calculation, light tracking algorithm based on Monte Carlo algorithm, object image refocusing algorithm and the like. By simulating that light of different wavelengths is emitted from the inside of a medium and subjected to medium absorption, scattering attenuation, medium emission, scattering enhancement and the like, the simulating calculation of the micro-lens light field imaging of a high temperature flame is performed. Through the simulating calculation, the temperature field of the high temperature flame can be reconstructed, and a theoretical basis is provided for calibration, measurement and the like of a light field camera.

Description

technical field [0001] The invention relates to a flame imaging simulation technology in the process of reconstructing the temperature of a high-temperature flame, in particular to a method for pan-scale analysis of flame light field detection based on a microlens array. Background technique [0002] The concept of multiscale has been applied in many fields of science and technology. Such as energy chemical industry, remote sensing detection, material processing, micro-electromechanical equipment and so on. [0003] However, the multi-scale concept that has been applied in the field of science and technology refers to: space-time, multi-scale in the binary system. Spatial multi-scale means that the process related to the phenomenon occurs in a space where the geometric scale changes by orders of magnitude; while temporal multi-scale means that the characteristic scales of different time periods in a physical phenomenon have orders of magnitude changes. [0004] The heat ra...
