稀释颗粒浓度通过芯直径超过颗粒直径的光纤探头进行检测。校准探头后，检查其对干舷浓度的应用。探头的校准曲线是通过检测已知浓度的自由落体粒子（终端速度）来确定的。此后，气体流化床的夹带流同时被探测并收集在旋风分离器中。探针信号与浓度之间的线性关系以及获得的良好干舷相关性证实了该技术的有用性。
Dilute particle concentrations are detected by optic fiber probe with a core diameter in excess of the particle diameter. After calibration of the probe, its application to freeboard concentrations is checked. The calibration curve of the probe is determined by detecting known concentrations of free-falling particles, at terminal velocity. The carryover stream of a gas-fluidized bed is thereafter simultaneously probed and collected in a cyclone separator. The linear relationship between probe signal and concentration and the good freeboard correlation obtained, confirms the usefulness of the technique.
