ABSTRACT:
A fall velocity indicator/viewer having a sampling compartment, a camera system, and an elongated tunnel for interconnecting the camera system to the sampling compartment. The camera system includes a video camera for continuously monitoring snowflakes as they naturally fall through a viewing area in the sampling compartment. The snowflakes are illuminated by a pair of strobe lights directly and in combination with reflected light from a pair of mirrors. In addition, a mirror in the tunnel provides a reflected view from the top of the snowflakes. The video camera is capable of thereby monitoring multiple views of snowflakes in a single video frame and provide sufficient data to analyze the physical characteristics of the snowflakes as well as aid in making velocity determinations and other observations of naturally falling snowflakes.
