An arrayed X-ray source rather than traditional X-ray tube with absorption mask was proposed to generate structured light,based on the analysis of grating absorption efficiency and the coherence of X-ray source.According to the intensity distribution of interferogram,the influence of absorption efficiency on visibility of interference fringes was presented.With respect to the state of art micro-fabrication,it was impossible to realize the absorption grating required.The optimal structure of arrayed source was given from the analysis of spatial coherence.In order to verify the feasibility of the method,an arrayed X-ray tube was fabricated and relative measurement was performed. |
