ABSTRACT:
In an imaging system comprising a source of light movable with respect to a writing element and projectable thereon to generate an image, a focusing means is provided for focusing a light source which generates a first beam of light of a wavelength selected to be actinic with respect to the writing element At least a portion of the first beam of light is absorbed by the writing element. The focusing means includes means for generating a second beam of light which is projectable onto the writing element and has a wavelength different than the wavelength of the first light beam. Means is provided which is responsive to the second beam of light to generate a signal to control the focusing means.
