A compact high-speed image capture system for a drum centrifuge
A compact high-speed image capture system for a drum centrifuge
Image capture and analysis provides an important source of data from physical model tests, but involves a far higher rate of data generation and storage than conventional instrumentation. This paper describes a new system on the drum centrifuge at UWA, which satisfies an elevated performance specification with a combination of new technologies. The system captures 5 megapixel images at a frequency of ≥10 Hz. It has 'live' viewing of the images, which is an imperative if using a centrifuge or any other experimental platform where the model cannot be viewed directly. The data is transmitted away from the experimental environment in 'real time', via a fibre optic transmission system that has sufficient robustness and data rate to satisfy the performance requirements even in the drum centrifuge environment. The camera is a solid state device, of machine vision standard. All of the hardware is ruggedized and sufficiently compact to operate within the confines of the 1.2 m diameter centrifuge ring channel. Example observations are included to verify the system performance, and details of the hardware are provided to allow this new technology to be deployed elsewhere by others within the physical modelling community.

Abstract
Image capture and analysis provides an important source of data from physical model tests, but involves a far higher rate of data generation and storage than conventional instrumentation. This paper describes a new system on the drum centrifuge at UWA, which satisfies an elevated performance specification with a combination of new technologies. The system captures 5 megapixel images at a frequency of ≥10 Hz. It has 'live' viewing of the images, which is an imperative if using a centrifuge or any other experimental platform where the model cannot be viewed directly. The data is transmitted away from the experimental environment in 'real time', via a fibre optic transmission system that has sufficient robustness and data rate to satisfy the performance requirements even in the drum centrifuge environment. The camera is a solid state device, of machine vision standard. All of the hardware is ruggedized and sufficiently compact to operate within the confines of the 1.2 m diameter centrifuge ring channel. Example observations are included to verify the system performance, and details of the hardware are provided to allow this new technology to be deployed elsewhere by others within the physical modelling community.
