This paper presents the method and experimental results of the fabrication of holographic grating. The holographic grating was fabricated by using an alternative setting of Michelson Interferometer. In general, the interference pattern produces by Michelson interferometer is a circle fringe pattern. By an alternative setting of the interferometer, we could obtain a fringe pattern that has a linear shape. The angles between the two arms of Michelson interferometer, cross-beam angle, were adjusted until a linear interference pattern occurs. The interference pattern was projected onto a screen where a photoresist film is located. The photoresist film functional as a collective material of an interference pattern, i.e., a holographic grating. The film is developed and then fixed by a chemical process. By the chemical process, the holographic grating is permanence recorded on the film. After the fabrication process, we analyzed the physical properties of the holographic grating. We also measured the grating space by Scanning Electron Microscope (SEM). Relationships between cross-beam angles and grating space are shown and discussed. Experimental results show that we could apply the proposed method to fabricate a holographic grating.
