开发了一套新型的三探头单纤光导探针测量系统，用于测量二维气泡速度。传感部件为光导探针，探针由平面分布的３个探头组成。在光路设计上，用光分路器取代传统的分光镜，使探针光路简单、易于调节，同时使系统紧凑、经济。针对二维气泡运动的特点，开发了无相关信号剔除算法和相关分析数据处理方法，用来计算气泡速度大小和方向角。用本系统测量气泡自由上升运动的速度，并与经验关系式计算结果相比较，二者的偏差在±３０％之内，说明本系统的测量结果具有一定精度
A new three-probe single fiber photoconductive probe measurement system was developed for measuring two-dimensional bubble velocity. Sensing components for the light guide probe, the probe consists of three probes distributed flat. In the light path design, the optical splitter replaces the traditional beam splitter, making the probe light path simple and easy to adjust, at the same time making the system compact and economical. In view of the characteristics of two-dimensional bubble movement, we developed a correlation-free signal culling algorithm and correlation analysis data processing method to calculate bubble velocity and direction angle. Using this system to measure the velocity of free rising movement of bubbles, and compared with the empirical relational calculation results, the deviation between the two is within ± 30%, indicating that the measurement result of this system has certain accuracy
