Abstract

The application of color-coded image separation to multiple-spark photography provides a simple method for recording shadow or schlieren photographs with arbitrary magnification, extremely high frame rate, short exposure time per frame, and no parallax. A color separation, multiple-spark camera is described which produces a sequence of three frames at 5 × magnification with a maximum frame rate of 10⁶/sec and an exposure time per frame of about 0.3 μsec. Standard 10.16-cm × 12.7-cm (4-in. × 5-in.) color film is used. This camera has been useful for observing liquid atomization processes and spray motion, since it enables direct measurement droplet size, location, velocity, and deceleration.
