    摘要: An optical recording method in which an effective recording sensitivity in the recording of image information on a photosensitive material is raised, whereby a productivity is enhanced owing to lowered energy (laser power) required for the recording or a heightened recording speed. An image is recorded by projecting a light beam onto the photosensitive material formed on a base material backing. The optical recording method includes the steps of: (a) successively outputting pulse light whose duty factor is at most 50%, from a light source; (b) modulating the pulse light output from the light source, in accordance with an image signal, and then projecting the modulated pulse light onto the photosensitive material; and (c) recording the image by causing the pulse light to scan the photosensitive material.

    摘要: In order to obtain a visually high quality image with excellent sharpness using a silver halide photosensitive material, it is necessary to reduce the ratio of EL light in the light output from a GaN based laser diode to 20% or less. For example, when the light intensity measured on a sheet of photosensitive paper is 0.05 mW, the thickness of a waveguide is 3 nm and the width of the waveguide is 3 μm, this condition is satisfied with a length of a resonator being 1 mm or less. In other words, a waveguide width W1 and a resonator length L are set such that the product of the waveguide width W1 and the resonator length L (W1·L) becomes 0.003 mm2 or less. This reduces the output ratio of the EL light, and a high quality image with excellent sharpness can be obtained when a silver halide photosensitive material is exposed.

    摘要: In an exposure device, a beam emitted from a light emitting point of a laser diode (LD) is limited by a slit. The slit limits a light beam in a direction orthogonal to an active layer of the LD. The exposure device has a moving mechanism which moves a plate in which the slit is provided, in a direction orthogonal to the plate. Object points are different at a beam and at flare light. Therefore, the plate is provided in a vicinity of the light emitting point in order to limit the light beam in the vicinity of the light emitting point, i.e., at a place near a point where a beam spot is smallest, and to be able to effectively block only the flare light.

    摘要: In an image exposing apparatus and an image exposing method, a deterioration of an image quality caused by stray light is suppressed, while both a sensitive level and a non-sensitive level are properly set in accordance with a type of photosensitive material. In the image exposing apparatus, a recording level setting unit calculates a recording level corresponding to a light amount level stored in a recording level light amount memory and sets the calculated recording level. A non-recording level setting unit calculates a non-recording level from an extinction ratio, which corresponds to a type of photosensitive material stored in a photosensitive material information memory, and the recording level. An output voltage setting unit sets an output voltage such that a detected voltage becomes equal to one of the recording level and the non-recording level.
