Visual Tracking of Real World Objects

Abstract

This paper describes the progress made towards tracking an object visually using a PIN diode attached to a dual mirror deflection system which enables the PIN diode to "optically point" to any position in two-space. A helium neon laser equipted with a similar mirror deflection system was used to point at the object being tracked. Actual objects tracked include a hand, a bouncing ping pong ball, and a white center on a black target attached to a moving metronome.
