Abstract
An optical scanner for reading indicia of variable light reflectivity, such as bar code symbols, having a light source for producing a light beam for scanning a target; a sensor for collecting the reflected light from the target; and various light collection systems, including a louver formed from an array of thin slats positioned adjacent to the sensor so that light directed along substantially only one angle reaches the sensor, as well as imaging/diffusing optical systems.
