| Abstract: | The principle of combustion field detection by using laser tomography is described,as well as the exploitation of laser tomography apparatus and the tool of image processing were introduced.The experiment of detecting flame fronts by laser tomography was made by employing a V-shaped premixed flame.The results show that the instantaneous geometry shape of flame wrinkles within the light sheet can be clearly differentiated.The contours of the flame fronts are precisely tracked through active contour method(ACM) from the digitized images of laser tomography,providing the basis for the quantitative analysis for flame wrinkles and their propagation. |
