Abstract

An inherent problem associated with fluorescent lamp illuminators is their poor axial uniformity. For xerographic applications, various techniques have been used to compensate for this illumination end fall off including use of butterfly slits, end reflectors and lamp length extension. These techniques, however, are not applicable for an optical system employing a linear type lens such as gradient index lens (GRIN) arrays.
