Hybrid particle filter based flame tracking algorithm is proposed in this paper.

In order to enhance the capacity of judgment, prediction and fault diagnosis in burning process, in this paper, we have done research on the flame image segmentation and flame tracking methods in the furnace.

In this paper,ways to design LiNbO_3 anisotropic acousto-optic device based on beam steering theory are studied.

A novel optimum design method of LiNbO3 anisotropic acousto-optic device based on beam steering is put forward, the accurate design parameters under different incident light angle and different number of transducers are systematically calculated.

The beam steering theory is studied to solve the problem that we can not get wider 3db Bragg bandwidth and high diffraction efficiency at the same time in the optimum design of LN anisotropic acousto-optic deflector (AOD) which is a crucial issue in the process to design an AO deflector.
