摘　　要：利用高散射性球和光纤制成了各向同性的光纤探头,对该探头接收不同方向入射光的特性测试表明,在10°～350°之间散射球输出信号相对变化率小于10%.用所制作的光纤探头探测散射介质中的相对能流率分布所得的实验结果与理论结果相符合.The isotropic light fiber probe is made by using a high scattering sphere and light fiber. The test for the probe receiving the incident light in different direction shows that the relative change rate of the response is less than 10% as the incident angle between 10°-350°. The detection result of the relative energy flux rate distribution in the medium can correspond to the theoretical result very well.
