Abstract: A scanning has a spinning mirror and an array of peripheral stationary mirrors which generate a scan pattern for reading bar codes. The backscatter from the bar code is collected by the peripheral mirrors and focused by an imaging lens. A housing is provided over the spinning mirror to reduce windage. The drive motor for the spinning mirror is mounted in front of the of the between the peripheral mirrors and the bar code. A backscatter detector is mounted behind the at the focal point of the imaging lens.
