We demonstrate a method to fabricate varied-line-spacing grating by employing elastic medium with variable vertical section. The advantages of this technique include continuous diversity of variation of line-space, high fabrication efficiency and low cost, etc. It is very difficult or unrealizable to produce this variation of line-space by traditional interference lithography. This kind of grating can be used in the optical position sensor and it can improve the precision of the sensor.
