| Summary: | This paper represents the configuration of an optical tomography sensor by using infrared emitters and phototransistors. The projection geometry of the sensor is based on the combination of two orthogonal and two rectilinear projection arrays. A fixture is designed for holding all emitter-receiver pairs in parallel. Selection of the phototransistor is explained so that the tomography sensor developed is free of noise caused by the surrounding environment. This paper describes all points to be considered when designing an optical tomography sensor. The results show that the developed system has the capability to detect the concentration profile of the flow. |
