Data from: Development of an optical flow through detector for bubbles, crystals and particles within oils

The characterization of bubbles or particles in an oil poses some unique challenges. In contrast to water solutions, the use of electrochemical detection approaches is more difficult in an oil. However, optical sensing systems have considerable potential in this area. Here we use a flow through channel approach and monitor the light propagation through this structure in an optical transmission sensor arrangement (OTS). This simple approach is demonstrated to be useful at detecting bubbles produced in the oil as a result of cavitation induced by high intensity ultrasound (HIU). The optical technique is shown to have an analytical basis. Bubble detection from an operating HIU source is shown to depend on position of the sensor with respect to the source. Critically, the bubble population can be followed for extended time periods after the ultrasonic source has been terminated. The detection of crystals is also demonstrated. Hence, this technique is ideal for the study of the effects of HIU on oils as they crystallize over extended time periods

Brief description of collection and processing of data: Crystal microstructure was determined using a polarised light microscope (PLM-Olympus BX 41, Tokyo, Japan) fitted with a digital camera (Infinity 2, Lumenera Scientific, Ottawa, Canada). In the most part, OTS data was collected using a DAQ card and was processed using VB2010 software utilising NI Measurement studio. Higher-resolution OTS data, e.g. for bubble oscillation examples, were collected using a digital oscilloscope. High-speed imaging video data was collected using a Photron APX RS camera and analysed using PFV Fastcam viewer 4 software.

Definition of acronyms, codes, and abbreviations: OTS refers to the optical transmission sensor device developed within this work. ΔOTS refers to the change in the OTS signal compared to baseline value. The signal output from the OTS device is given as a voltage, Vopto, recorded as a function of time, t.
