ABSTRACT:
A facsimile optical apparatus that comprises an optical head includes planar integrated optics. The head is fabricated with planar reflective lenses situated to focus light onto an image surface, and an array of planar reflective lenses to focus light reflected off the image surface onto an array of light detectors. Optionally, the light generating and the light detecting elements are fabricated on the substrate containing the planar reflective lenses, resulting thereby in a very compact arrangement. When image lines need to be accepted that are larger than the size of arrays that can economically be fabricated on a single substrate, integrated aligning means are provided to couple a number of substrates to each other and to form thereby a larger working element.
