Abstract
An optical scanner is disclosed which, in one embodiment, uses a reflection surface on a vibrating element having at least two modes of vibration in at least two respective planes to produce an image scanning beam. Each of the modes has an associated resonant frequency and the two resonant frequencies of the vibrating element are not integer multiples of one another. In another embodiment, a reflective element is used to bounce a light beam from the reflection surface back to the reflection surface to increase the angle of scanning of a light beam. The reflective element may be semitransparent which allows the scanning beam to be detected through the range of scanning to ensure proper scanning. The optical scanner is particularly useful as a hand-held bar code scanner.
