DEFINITION

Classification: 235/462.4

Pattern mirror detail for rotating mirror:

(under subclass 462.39) Subject matter including a polygon which receives the light from a light source and reflects that light in form of a more complex light pattern to the code to be read.

(1) Note. The complex light pattern is used to capture a bar code at different angles.
