Abstract:
A method and apparatus comprising an imaging system (10) with safety control for imaging target objects having a scanning arrangement (14) including a sensor assembly (22) for capturing an image from a target object. The sensor assembly (22) has a field-of-view focused by an optical arrangement (24) onto a sensor array (28). The imaging system further comprises an illumination assembly (18) having a housing (30), illumination source (38), light pipe (42), and projection lens (36). The illumination assembly (18) provides light energy toward the sensor assembly field-of-view for illuminating the target object to be imaged on the sensor array (28). The light pipe (42) comprises a multi-walled tapered body (52) having an input face (40). The walls of the body (52) create mirrored images of the illumination source (38), together with the projection lens redistribute the amount of light energy directed at the eyes of a human.
