A wedge shaped platen scanner sequentially records opposing pages of a bound document positioned thereon. A dichroic mirror is positioned between the surfaces of the wedge shaped platen. The two sides of the opposing pages of the bound document are exposed by light having different wavelengths. One side is exposed by a flash lamp that emits light with a wavelength that forms an optical path through the dichroic mirror and onto an imaging station. The other side is exposed by a flash lamp emits light with a wavelength that forms a reflective path off of the dichroic mirror and onto the imaging station. A controller insures that the opposing pages of the bound document are sequentially illuminated by the two flash lamps. Images of opposing pages of the bound document are focused through optics onto the imaging station. In one arrangement, the imaging station is a two-dimensional array of detectors which sense an image of a page of the bound document projected thereon. In another arrangement, the imaging station is a photoconductive belt which when exposed by either flash lamp records a latent image thereon. In either arrangement, a one page imaging station records opposing pages of a bound document either electronically or on print media, one page at a time.
