An image registration system for determining a relative location of a first pattern and a second pattern includes a fiducial having a fiducial origin, a first side, and a second side. A first camera captures a first fiducial image of the first side of the fiducial and the fiducial origin and a first pattern image of the first printed pattern. A second camera captures a second fiducial image of the second side of the fiducial and a second pattern image of the second printed pattern. An image registration controller processes the first fiducial image, the first pattern image, the second pattern image, and the second fiducial image to determine the relative location of the first pattern and the second pattern.

Multiple sided media pattern registration system

A method of printing includes printing first and second patterns at first and second locations on first and second sides of a media using first and second printheads, respectively. First and second fiducial images including a fiducial origin are captured using first and second cameras, respectively. First and second pattern images of the first and second patterns are captured using the first and second cameras, respectively. The locations of the first and second patterns relative to the fiducial origin are determined using an image registration controller. A relative printed location of the first pattern and the second pattern is determined. A deviation is determined by comparing the determined relative location of the first and second printed patterns with an intended relative location of the first and second printed patterns. The determined deviation is compensated for by adjusting at least one of the first and second printheads so that subsequently printed first and second pattern have the intended relative print locations.

Printing registered patterns on multiple media sides

A printing system includes a media transport system and first and second printheads that print first and second patterns on first and second sides of the media, respectively. An image registration system includes a fiducial including an origin and first and second sides. A first camera captures a first fiducial image of the first side and origin and a first pattern image of the first pattern. A second camera captures a second fiducial image of the second side and origin and a second pattern image of the second pattern. A registration controller processes the first and second fiducial images and pattern images to determine a relative position of the first and second patterns. A print controller, controlling printhead operation, adjusts the registration of subsequently printed patterns on at least one of the first and second sides of the media based on the determined relative pattern position.

Printing system having multiple sided pattern registration

A method of determining a relative location of a first pattern and a second pattern includes providing a fiducial including a fiducial origin, a first camera, a second camera, and an image registration controller. A first fiducial image of the fiducial origin is captured using the first camera. A second fiducial image of the fiducial origin is captured using the second camera. A first pattern image of a first pattern is captured using the first camera. A second pattern image of a second pattern is captured using the second camera. A first location of the first pattern relative to the fiducial origin is determined using the image registration controller. A second location of the second pattern relative to the fiducial origin is determined using the image registration controller. A relative location of the first location and the second location is determined using the image registration controller.

Registering patterns on multiple media sides

A laser array and method of making same has precision fiducial marks that aid in the alignment of the laser array. The invention requires forming additional optical features adjacent to the laser array that is used to write fiducial marks on an opposite surface in the medium containing the laser array. Fiducial marks are formed when high intensity collimated beams of light are directed through the optical features onto a treated portion of the transparent medium. Fiducial accuracies of 1 micron are possible by using this approach.

Laser array and method of making same

A method of forming fiducial marks on a micro-sized article has at least one optical feature adjacent the micro-sized article that focuses a collimated beam of light onto a surface opposite the mounting surface of the micro-sized article. Fiducial mark is formed on the surface that enables precise alignment of the micro-sized articles.

Fiber optic array and method of making same

A method of manufacturing a microlens array requires at least two fiducial marks formed on a surface of a transparent medium opposite the microlens array. Additional optical features formed on the transparent medium adjacent the microlens array enables precise locationing of fiducial marks on an opposing surface when such surface is exposed to a collimated beam of light. The location of fiducial marks using the method of the invention is about 1 micron or less.

Method and manufacturing a precisely aligned microlens array

A double-sided microlens array and method has a plurality of first microlenses on a first surface opposite a plurality of second microlenses on a second surface of a transparent medium. At least two optical features are arranged on either of the first or second surfaces to form fiducial marks on the opposing surface in the transparent medium. The fiducial marks enable precise alignment of the microlenses in the first and second plurality of microlens arrays.

A microlens array has a plurality of microlens supportedly arranged on a first surface of a transparent medium. At least two optical features are formed on a second surface opposite the first surface. Fiducial marks are formed on the second surface by a beam of collimated light directed onto the optical features and focused onto the second surface. Fiducial marks enable precise alignment of the microlenses in the microlens array.
