Xiang Qin LIN∗, Liang Dong FENG, Hao ZHANG. Chinese Chemical Letters Vol. 17, No. 4, pp 493-495, 2006.

Recording surface tension curves at a mercury drop during potential scanning based on photo-sensitive detection system.
Optical imaging methods can be used for accurate surface tension measurement, however, continuous tension curve is hardly obtained by this technique.
