Abstract: Aviation sylphone is a high precise element and widely employed in air,oil,chemistry and coal industry.Based on grating diffraction principle,we developed a microcomputer automatic measurement system for checking the displacement of aviation sylphone.The system utilizes a He Ne laser with 8mW power output as the light source to provide the 0.53μm resolution and ±0.8μm measurement accuracy.
