Abstract
A programming apparatus and method for optical scanners which employs bar code labels to convert one optical scanner into a mentor scanner and another optical scanner into a student scanner. A lightweight housing made of opaque plastic has a center portion and first and second end portions, the center portion containing a cavity, and the first and second end portions containing apertures therethrough and into the cavity. Within the cavity, two parallel diffusion screens are separated by a distance sufficient to convert a light beam from the mentor scanner into a plurality of point sources of light for reception and detection by the student scanner. Sockets within the end portions position the scanners and seal out ambient light.
