An imaging head () for writing an image on a substrate () includes an array of emitters () comprised of groups of emitters (); imaging lens () that focuses light from each group onto the substrate; and wherein light from each group is focused at a different depth relative to a surface of the substrate.

Imaging head for 3D imaging

The present invention relates to a system for optically adjusting a computer-to-plate (CTP) imaging head which includes an a light source (), optical fiber () for transmitting light emitted from the light source; an imaging lens () for focusing light emitted from a distal end of the optical fiber () on a substrate; wherein a portion of light striking the substrate is reflected back to the distal end of the optical fiber; a fiber optic coupler () in the optical fiber which transmits the reflected light to a light detector (); wherein the light detector measures intensity of the reflected light; and a control unit configured to adjust the imaging head according to the intensity of the reflected light.

System for optically adjusting an imaging head

Beam shapers, imaging heads formed using such beam shapers and methods are provided that are adapted to shape a light beam for use in imaging. In accordance with one method described herein a light beam is received and the light beam is reflectively scrambled to form generally homogenous light having a non-circular shape. The homogenous light is delivered to a circular core multimode light path that shapes the light beam so that light exiting the circular core multimode light path comprises circular shaped homogenous light.
