    摘要: An anamorphic projection optical system is disclosed that takes in a relatively low intensity two-dimensional light field, and anamorphically images and concentrates the light field to generate a substantially one-dimensional, high intensity line image extending in a process direction on an imaging surface. The optical system includes a process-direction optical subsystem (137E) formed by one or more cylindrical/acylindrical lenses (138) in an all-refractive arrangement, or a combination of cylindrical/acylindrical lenses and mirrors to generate the line image with sufficient energy, for example, to evaporate fountain solution from the imaging surface. The anamorphic optical system also includes a cross-process-direction optical subsystem (133E) formed by one or more cylindrical/acylindrical lenses (134E) and an optional cylindrical/acylindrical field lens to image the modulated light field in the cross-process direction. The anamorphic projection optical system facilitates simultaneously generating multiple pixel images of the line image, thus facilitating a printing at 1200 dpi or greater.

    摘要: A single-pass imaging system (100) utilizes a light source (110), a spatial light modulator (120) and an anamorphic optical system (130) to form a substantially one-dimensional high intensity line image on an imaging surface (e.g., the surface of a drum cylinder). The light source (110) and the spatial light modulator (120) are used to generate a relatively low intensity two-dimensional modulated light field in accordance with an image data line such that each pixel image of the line is elongated in the process (Y-axis) direction. The anamorphic optical system (130) utilizes a cylindrical/acylindrical optical element to anamorphically image and concentrate the modulated light field in the process direction to form the substantially one-dimensional high intensity line image. The line image is generated with sufficient energy to evaporate fountain solution from the imaging surface. The imaging system simultaneously generates all component pixel images of the line image, thus facilitating a printing apparatus capable of 1200 dpi or greater.

    摘要: An imaging system includes a first off-axis illumination source for providing a first illumination field (30) at a surface of an illumination modulator (32) such that when the modulator (32) is in a first non-activated mode a zero-order reflected illumination field (34) is directed toward a first illumination blocking device (36), and when the modulator (32) is in a second activated mode one first order reflected illumination field (40) is directed toward the imaging surface (38) while another first order reflected illumination field (42) is directed toward a second illumination blocking device (44).

    摘要: A gap switching mechanism 30 is installed for switching the gap between a recording head 15 and a recording medium in a predetermined position during transverse travel of a carriage 10. The carriage 10 has a recording head 15 downwardly mounted thereon and is swingably and turnably supported at one side of its lower end by a guide shaft 11 in the form of a round shaft. A switching block body 13 having a plurality of abutments 52, 53 with different heights in opposed relation to the upper-end slide portion 12a of a frame 12 longitudinally extending along the back of the carriage, is turnably supported by the carriage. A first pusher 56 is positioned at the left-hand end of the frame to be allowed to abut against the switching block body 13, so that the abutting changes the turning posture of the first pusher to bring the abutment 53 into sliding relation to the frame 12, thus providing a small gap. A second pusher 57 is positioned at the right-hand end of the frame to be allowed to abut against the switching block body 13, so that such abutting changes the turning posture of the first pusher to bring the abutment 52 into sliding relation to the frame 12, thus providing a large gap.

    摘要: A projection optical system has first to fourth lens groups (51) to (54) provided in this order from a SLM, a mirror (32) having an opening is provided between the first lens group (51) and the second lens group (52), and an aperture plate (132) is provided between the third lens group (53) and the fourth lens group (54). Zeroth order light which is signal light from the SLM passes through each opening of the mirror (32) and the aperture plate (132) to be guided to a recording medium, and a part of first order diffracted light is reflected by the mirror (32) to be guided outside and received by an external light-block water-cooling jacket. The rest of the first order diffracted light is blocked by the aperture plate (132), and heat generated by light blocking is removed by a cooling mechanism connected to the aperture plate (132).

    摘要: A method for cooling and pressurizing a laser imaging head (8) including a laser source (12), a light valve (10) for modulating the light (24) from the laser source (12), and optics for transferring the modulated light (26) to a medium (6). The method including enclosing the imaging head (8) within a non-hermetically sealed enclosure and providing a flow of cooled air at a predetermined cool air temperature and at a controlled positive air pressure into the sealed enclosure through an inlet (22) from a vortex tube (14) operating from compressed air. The cooled air flow and the predetermined cooled air temperature are controlled by the vortex tube (14) in order to maintain an operating temperature of the components within the imaging head (8) within a predetermined operating range and to maintain the positive air pressure within the sealed enclosure with respect to ambient air pressure outside of the sealed enclosure due to the controlled flow of cooled air entering the sealed enclosure.
