Abstract [en]

This paper discusses a new technique for imaging in smoke. When using regular light sources, light is scattered by the smoke making it difficult to see different objects. The same effect can be experinced when driving through fog with headlights full on. This effexty can be avoided or heavily reduced by implementing a new technique which employs a pulsed laser beam as light source. Technology exists for undersea imaging. We designed, based on previous work, a system for smoke imaging in air. The laser emits short pulses which are reflected by objects as well as scattered by the smoke. The laser pulses are detected by a high-speed CCD camera and by a gating technique the scattered light is reduced. The image is presented on a monitor. A model of the system was tested by appropriate experiments to evaluate possible image improvments.
