    摘要： A scanning optical system is used to re-form an original image on a CCD line sensor. The optical system has an object side lens unit, a mirror and an image side lens unit. The object side lens unit condenses light from the object. The mirror is arranged between the object side lens to deflect the light having passed through the object side lens unit for scanning. An exit pupil of the object side lens unit coincide with an entrance pupil of the image side lens unit.

    摘要： An optical recording head which decomposes light emitted from a light source into three primary colors with rotation of a color wheel, emits the light linearly through an optical fiber array, illuminates an optical valve array through an integrator and an illuminating optical element array and exposes a photographic paper to light modulated by the optical valve array through an imaging optical element array. The integrator is formed by arranging two mirrors in parallel to each other, and a rod lens is provided between the mirrors. The rod lens has a refracting power to decrease the divergent angle of the light emergent from the optical fiber array.
