Abstract
A module and an arrangement for, as well as a method of, generating a generally uniform distributed line pattern of light on a symbol to be read by image capture, include a light source for generating light along an optical axis in a distribution having different extents along intersecting directions generally perpendicular to the axis, and an optical component for receiving, and for optically modifying, the light from the light source to generate the generally uniform distributed line pattern of light on the symbol. The optical component includes a plurality of compound conic elements spaced apart from one another along one of the directions. Each compound conic element has a pair of conic segments for modifying the light along the one direction. A collimating lens modifies the light along the other of the directions. A solid-state imager has an array of image sensors for capturing return light from the symbol over a field of view having different extents along the intersecting directions.
