Advanced Real-Time Digital Microscopy of Foaming Processes, TAPPICon22

This paper presents in-situ optical microscopy measurements of aqueous foams in foaming processes. It presents methods for providing detailed information on foam quality parameters, such as foam density and foam homogeneity in real time from the process. This study evaluates the performance of transillumination and front-light illumination in imaging of foams. The tests show very good results for the transillumination approach. Limitations of image-based optical technique have been discussed, and the precision of bubble size distribution measurement has been assessed with a certificated reference substance. The measured foam density has been compared with the reference foam density in the density range of 100-300 g/L providing a linear correlation with R2-value of 0.99. Finally, we present some guidelines for successful foam measurements.
