    摘要： Optimization of distances between each of an array of imaging devices and the surface of an oppositely disposed rotating drum is accomplished without disturbing the mechanical mounting of the imaging devices. For each device, an optimal distance from the recording construction is established; at this optimal distance, corresponding to substantially proper focus, maximum energy density is delivered to a recording medium on the drum. Rather than alter the actual device-to-drum distance to conform to this optimum, the optical paths between the devices and the drum are changed by varying the spacing between the radiation source (e.g., the end of a fiber-optic cable) and the assembly. This alters the point of focus, and therefore has the same practical effect as moving the device itself. The invention also provides a technique for determining the optimal device-to-drum distance by means of a sequence of imaged regions applied at different device-to-drum distances.

    摘要： An illumination system (10,30,100,130,150,180,200) for hard copy applications including an elongated array (32) of light emitting elements (34) in combination with a light mixing element (42,46) for mixing the light from the individual elements in the lateral or cross-process direction. A curved array (32) or linear array (102) of light emitting elements with an aspheric lens (108) may be utilized, with a cylindrical lens (36,106) compressing the beam of light in the vertical or process direction. The light mixing elements (42,46) are preferably comprised of holographic diffusers. Sufficient mixing of the light from the array is achieved in the cross-process direction whereby a reduction in light output of one light emitting element does not generate a significant localized reduction in intensity at the elongated spatial light modulator. Preferably, the spatial light modulator is a digital micromirror device (DMD), but may also comprise of other devices including those of the transmissive type, including liquid crystal devices.

    摘要： A compact optical system for imaging an array of light emitters, particularly an individually addressable laser diodes array, onto a recording surface, whereby the image of each emitting region is spread in the cross direction to a width approximately equal to its length dimension. The system consists of a main non-anamorphic imaging lens assembly and a single cylindrical lens disposed between the array and the imaging lens assembly, with its focal line parallel to the array's centerline. There will occur a spread of the short dimension of the imaged emitting regions due to defocusing at the recording surface. Also, the numerical aperture of the emitted beams in the transverse axis is reduced prior to entry into the imaging lens assembly.

    摘要： An image forming apparatus which can obtain a high-quality image although the adjustment of alignment is easy or unnecessary is provided. In the apparatus, light beams emitted from light-source means, in which a plurality of light-emitting devices are arranged in a one-dimensional direction, are focused onto a surface of a recording medium by a lens array formed by arranging a plurality of condensing lenses in a scanning direction in two lines so as to staggerly and closely place lenses in one line on lenses in another line. When the radius of a field of view of a single condensing lens is represented by X 0 , the diameter of the condensing lens is represented by D, and a degree of overlap is represented by m = X 0 /D , the lens array is formed so as to satisfy the following condition: 1.85

    摘要： In order to improve the resolution of a LED printing head by a comparatively simple method, optical shutters (28) are provided between two rows of rod lens arrays (26) and LED arrays (18) correspondingly to the rod lens arrays (26). The central optical axes of rod lenses (24) in the rod lens arrays (26) are inclined by an angle of inclination theta in the opposite directions with respect to the direction of perpendicular lines passing the centers of the light-emitting surfaces of LED's (14), and signal light sent out from the LED's (14) is condensed on a photosensitive surface (20) alternately via predetermined rod lens arrays (26) so that one line is formed on the photosensitive surface (20).
