Abstract
A new method for the determination of the temperature of single droplets is presented. The method utilizes the analysis of the near field scattered light distribution. This distribution exhibits sharp peaks, the so-called glare points, if observed through a lens with finite aperture. The ratio of the brightnesses of the glare points of the zero and the first orders shows a monotonic dependence on the index of refraction. The ratio is measured and the temperature is calculated by means of the known dependence of the index of refraction on the temperature.
