Principle of evaluate laser beam quality based on laser spot characteristics is analyzed. In allusion to simple evaluation of laser beam quality in non laboratory conditions,a method of extracting laser-plot image based on OTSU algorithms is proposed. Detailed algorithms are shown while experiments are given using three laser range finders. The experimental results indicate that laser-plot image can be extracted from photographic paper utilize OTSU algorithms,what’s more,binaryzation spot image and the extracted profile features can be used to judge the merits of laser beam quality of different laser range finder effectively.
