Design a cage-typed light field camera system for flame measurement

A cage-typed light field camera system for flame temperature measurement is designed and fabricated to obtain flexibility to change its components and parameters. In this case, it is flexible to change the components of the light field camera to compare the performance of different optical parameters on the measurement accuracy of the flame. The structure and components of the cage-typed light field camera system are presented and discussed. At different parameters, their results are compared to evaluate the performance of the light field camera. The results indicate that the cage-typed system has good imaging performance for different parameters. To validate the proposed system, the self-assembled camera is utilised to retrieve the flame temperature from light field flame images through the use of deconvolution method
