Therefore condensation of water leads to a visible optical defect. This paper presents a new approach for determination of the droplet size using colour phenomena in totally reflected light. It is based on a model of the generation of colour patterns by interference of several rays of light each multiple totally reflected inside condensed droplets. The droplet size may be determined by the colour if the contact angle is known. Measurement of both droplet size and colour all 2006Nürenberg eng 978-3-9810993-0-0 Wetzlar, Dietmar, Bernd Henning, Sascha Nolte, and Jens Klahold. “Investigation of Colour Phenomena in Condensed Water Droplets,” 2006.
