A new photographic method is developed to be able to take a whole shape of a diesel spray in the wide visual field with the high spatial resolution. The photographic system is composed of a self-made high-magnified projector and a large format silver halide film. The high-magnified projector has two objective lenses with long-working distance and high spatial resolution. Using large format film, this enables the measurement of each droplet in wide visual field. In the experiment, laser transmitted light has been developed to investigate the droplet diameter of diesel spray. The light source was the second harmonic of Nd: YAG laser. As a result, the fine image of a spray periphery was taken by this system. There is the possibility of measurements the droplet diameter of the whole spray by using photographic system.
