چکیده انگلیسی
A compact and stable two-axis Lloyd's mirror interferometer based on a new non-orthogonal type of mirror-substrate assembly is designed for fabrication of 100â¯mmâ¯Ãâ¯100â¯mm large-area two-dimensional (2D) diffraction scale gratings in a research laboratory or a small-scale manufacturing facility. At first, the required mirror sizes used in the new non-orthogonal type and the conventional orthogonal type are compared based on geometrical analysis. It is identified that the width of the mirror can be reduced to half in the non-orthogonal type while the required mirror height and the expanded laser beam diameter are comparable to those in the orthogonal type. The shorter mirror width makes it possible to design a compact mirror-substrate assembly so that the overall interferometer can be realized in an overall size of 1480â¯mmâ¯Ãâ¯730â¯mm for mounting on a commercially available general-purpose 1500â¯mmâ¯Ãâ¯1000â¯mm vibration isolation table for use in research laboratories. It is then verified by simulation that the selected laser source and the designed beam expansion assembly, which are the other main parts of the interferometer, are effective for fabricating the designed grating structures. Experiments are also carried out to demonstrate the feasibility of the constructed interferometer for fabricating 100â¯mmâ¯Ãâ¯100â¯mm 2D scale gratings with a short period of 1â¯Î¼m.
