We reported a new type of optical fiber sensor (OFS) for gas-liquid two phase flow. The diameter of minimum measurable gas bubble is 100-200um, range of void fraction is 0-100%, response time is l0μs, measure error is about 5% for measuring void fraction in air-water. There are two kinds of sensing head. The design and performance of sensing head are described.
