摘要

我们提出了使用光谱域光学相干层析成像（OCT）的自动流量测量。流动模体由一个玻璃管道组成，测试悬浮液流经其中。对采样OCT图像进行二值化处理，确定探测光束与导管之间的夹角，得到真实的流速。体积流量测量的数据处理是全自动的。通过处理一个包含5对图像的数据集，得到流量结果大约需要4 s。实测流量结果与确定值吻合。为了保证测量精度，还讨论了两个扫描平面之间的距离对测量流量的影响。

Automatic data processing for phantom flow measurement using spectral domain optical coherence tomography

We present automatic flow volume measurement using spectral domain optical coherence tomography (OCT). Flow phantom consists of a glass duct with the test suspension flowing through it. Sampled OCT images are binary processed to determine the angle between the probing beam and the duct to get real flow velocity. Data processing for volumetric flow measurement is fully automatic. It takes about 4 s to get flow volume result through processing one dataset containing five image pairs. Measured flow results coincide with the settled values. Effects of the distance between two scanning planes on the measured flow are also discussed to ensure measurement accuracy.

期刊介绍： Flow Measurement and Instrumentation is dedicated to disseminating the latest research results on all aspects of flow measurement, in both closed conduits and open channels. The design of flow measurement systems involves a wide variety of multidisciplinary activities including modelling the flow sensor, the fluid flow and the sensor/fluid interactions through the use of computation techniques; the development of advanced transducer systems and their associated signal processing and the laboratory and field assessment of the overall system under ideal and disturbed conditions. FMI is the essential forum for critical information exchange, and contributions are particularly encouraged in the following areas of interest: Modelling: the application of mathematical and computational modelling to the interaction of fluid dynamics with flowmeters, including flowmeter behaviour, improved flowmeter design and installation problems. Application of CAD/CAE techniques to flowmeter modelling are eligible. Design and development: the detailed design of the flowmeter head and/or signal processing aspects of novel flowmeters. Emphasis is given to papers identifying new sensor configurations, multisensor flow measurement systems, non-intrusive flow metering techniques and the application of microelectronic techniques in smart or intelligent systems. Calibration techniques: including descriptions of new or existing calibration facilities and techniques, calibration data from different flowmeter types, and calibration intercomparison data from different laboratories. Installation effect data: dealing with the effects of non-ideal flow conditions on flowmeters. Papers combining a theoretical understanding of flowmeter behaviour with experimental work are particularly welcome.
