摘　　要：介绍一种基于微小可变的双折射率元件的先纤压力传感器,它能有效地测量压力的变化,表现出很高的压力灵敏度.该光纤压力传感器由于采用了色彩敏感技术,对先强表现出不敏感性.An optical fibre pressure transducer based on minor variable dual refractivity is introduced. The transducer is able to measure the pressure change effectively and shows excellent sensitivity to pressure. Because of using color-sensitive technology the optical fibre pressure transducer is not sensitive to intensity.
