摘要： The image recording method and image recording apparatus synchronize phase of a light deflector with rotation of a drum in response to the drum start point detection signal generated each time the drum rotates once, expose the two-dimensional image of one frame formed by a group of light sources disposed two-dimensionally onto the recording medium while causing the image at rest on the recording medium relatively thereto, thereafter move the optical system in the auxiliary scanning direction by an integral multiple of a pixel pitch forming one frame as well as deflect an angle of the light deflector in the main scanning direction by one frame so as to expose the next frame and on for one rotation of the drum. When the position is dislocated in the auxiliary scanning direction at the time the recording medium is to be exposed in a subsequent one rotation of the drum, the method and apparatus correct the dislocation of the position in the auxiliary scanning direction by changing an auxiliary scanning movement speed in a non-exposure time zone between the previous and subsequent rotations of the drum.Accordingly, the method and apparatus can prevent the occurrence of streaked unevenness in the surface exposure and spiral exposure.

摘要： An image-wise exposure apparatus comprises a light source for producing recording light, to which a photosensitive material is to be exposed, and a spatial modulation device provided with a plurality of picture elements located in the form of a two-dimensional array. The spatial modulation device raster-scans the picture elements and thereby carries out spatial modulation of the recording light. A picture element shifting device changes the optical relationship between the spatial modulation device and the photosensitive material. A controller sets all of the picture elements of the spatial modulation device to a totally closed condition for a single frame period and drives the picture element shifting device while all of the picture elements of the spatial modulation device are being in the totally closed condition. Effects of a picture element shifting operation are thereby obtained sufficiently, and image-wise exposure is carried out quickly.

摘要： An image-wise exposure apparatus comprises a light source for producing recording light, to which a photosensitive material is to be exposed, and a spatial modulation device, which is provided with an array of picture elements and carries out spatial modulation of the recording light. A shifting device changes the optical relationship between the spatial modulation device and the photosensitive material. In cases where the number of exposure dots formed on the photosensitive material is increased by a factor of m with a picture element shifting step carried out with respect to a certain array direction of the picture elements, and the period, with which periodical nonuniformity in image density obtained by exposure occurs with respect to the array direction of the picture elements when the shifting step is not carried out, is n times as long as the pitch between the picture elements, the distance of shift of the picture elements with respect to the array direction of the picture elements is set to be approximately (n.+-.1)/m times as long as the pitch between the picture elements.

摘要： An optical waveguide device for coupling an external wave with a guided wave by means of a grating coupler formed on an optical waveguide device which lies on a substrate. The grating coupler is further coated with a cladding layer. An external wave is transformed into a guided wave after being diffracted by a first grating coupler, and travels along the waveguide to a second grating coupler. The guided wave is then subjected to diffraction by means of the second grating coupler, whereupon a minus first-order wave is diffracted only toward the substrate, whilst other waves of higher order are respectively diffracted toward the cladding layer and the substrate. The wave diffracted toward the cladding layer is totally reflected from a cladding layer boundary furtherst from the substrate, thereby passing through the substrate. The diffracted wave thus reflected interferes with the other wave of the same order diffracted to the substrate, thereby weakening each other.
