Laser induced fluorescence method has been employed for the remote, non-intrusive and instantaneous measurements of a fuel droplet flame. A fuel droplet was doped with naphthalene and TMPD. The fluorescence emission spectra from a droplet subjected to the incident nitrogen laser were measured with an image intensified optical multichannel analyzer. The results showed that a droplet temperature could be determined from the result of the ratio of fluorescence emission intensities at two different wavelengths. The ambient pressure was found to little affect the intensity ratio. The oxygen concentration was found to affect the fluorescence intensity ratio in high-pressure ambience.
