Abstract
A televising apparatus is provided in a chamber of a snowfall testing system in which various testing conditions may be varied which effect the characteristics of particles of snow generated in the chamber. The televising apparatus has a television camera with an object lens for televising the particles of snow falling in the chamber, and a film feeder for feeding a transparent film, onto which the particles fall, past the object lens. A television camera transfer unit moves the television camera and object lens relative to the transparent film such that the particles falling thereon may be properly and fully televised. Furthermore, a focus regulator is used to move the film feeder and film relative to (toward and away) from the object lens so that the particles falling on the film may be focused. By televising the particles, results of the testing conditions are obtained which can be used to determine the effects of the testing conditions in generating snow within the chamber.
