Abstract
A system for scanning objects having a linear array sensor, adapted to detect light input signals, is provided. A lens is optically connected to the linear array sensor, and is adapted to receive and transmit an optical image located in a field of view along a lens axis to the linear array sensor. A light source which generates an illumination stripe in general linear alignment with the lens axis is provided. A cylindrical lens is positioned between the light source and an object to be scanned. The cylindrical lens adapted to collect, transmit and focus light from the light source to form the illumination stripe.
Claims21
A system for scanning objects in an object scanning area on a support surface comprising:
- a linear array sensor adapted to detect light input signals;
- a lens optically connected to the linear array sensor, the lens adapted to receive and transmit an optical image located in an optical field of view of the linear array sensor;
- a light source with a lens that produces an illumination plane that has a height that extends over a depth of field and a width that extends across the support surface so that an illumination stripe is formed on a surface of the object in the optical field of view;
- and
- the illumination plane and the optical field of view are coplanar over the depth of field in the object scanning area.
