摘要： 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.

摘要： A system for measuring a distance to a substrate includes a first light source, emitting a first wavelength on a region of the substrate though a lens. A second light source emits a second wavelength region of the substrate through the lens. A first and second detector are configured to detect the first and second wavelength light reflected from the substrate. A processor is configured to compute a first response function wherein the first response function represents reflected light intensity emitted from the first light source as a function of the distance between the imaging device and substrate. A second response function represents reflected light intensity emitted from the second light source as a function of the distance between the imaging device and substrate. A ratio response function represents the ratio of the first and second response function as a function of distance between the imaging device and substrate.
