    摘要: A quantum cascade laser is provided that is constituted as a superlattice device configured by repeatedly overlaying AlSb or GaAlSb layers and GaSb layers and forming electrode layers at the opposite ends thereof, wherein the thickness of the GaSb layers constituting quantum wells for performing stimulated emission of light is defined so that the energy difference formed between the ground state and the first excited state in the GaSb layers becomes the LO phonon energy of GaSb. The quantum cascade laser lases at lower frequency than conventionally and has a structure that is easy to fabricate.

    摘要: An image recording apparatus has light emitting elements arranged in a main scanning direction and an imaging optical system which images light from the light emitting elements on a recording medium. An image is recorded on the recording medium by imaging light from the light emitting elements through the imaging optical system while moving the recording medium in a sub-scanning direction. The imaging optical system is formed of a first optical system consisting of biaxial optical elements, each having a refractive index profile in the main scanning direction and a refractive index in the sub-scanning direction, arranged in the main scanning direction, and a second optical system consisting of an optical element disposed on the light incident side of the first optical system and having a refractive power to light components propagated in the sub-scanning direction but no refractive power to light components propagated in the main scanning direction.

    摘要: Stimulating rays produced by a line light source are linearly irradiated onto an area of a stimulable phosphor sheet, on which a radiation image has been stored. Light, which is emitted from the linear area of the sheet exposed to the linear stimulating rays, is received and photoelectrically converted by a line sensor. The line sensor comprises a pair of one-dimensional CCD image sensors. Light receiving regions of the one-dimensional CCD image sensors are located close to each other with respect to a direction normal to the length direction of the linear area of the sheet and with a fine gap intervening between the light receiving regions.

    摘要: Stimulating rays produced by a line light source are linearly irradiated onto an area of a stimulable phosphor sheet, on which a radiation image has been stored, and light emitted from the linear area of the sheet upon stimulation is photoelectrically converted by a line sensor. Outputs of several pixel regions of the line sensor, which are adjacent to one another along the length direction of the linear area of the sheet and have widths taken in the length direction of the linear area of the sheet such that a sum of the widths is equal to the width of one pixel in a final image, are added together in order to constitute an image signal component representing one pixel in the final image.

    摘要: In a two-side radiation image reading method wherein a stimulable phosphor sheet storing a radiation image is scanned by stimulating rays and light emitted from the front and back sides of the sheet is photoelectrically detected by photoelectric reading means separately located on the front and back sides of the sheet to obtain two image signals representing the radiation image to be subjected to addition processing or the like for obtaining a final image, shading correction data and/or fading correction data are obtained in advance and shading correction and/or fading correction is carried out on the image signals by using the correction data having been obtained. While an area equivalent to one side of the stimulable phosphor sheet (whose number of main scan lines is 4320) is being scanned, reading of the sheet is switched between the front and back sides and sensitivity of photoelectric reading means is also changed (to standard, semi-high, and high).

    摘要: In a light beam scanning recording apparatus, a recording material is scanned with a laser beam having been produced by a single-longitudinal-mode semiconductor laser and having been directly modulated in accordance with an image signal, and a continuous tone image is thereby recorded on the recording material. A device superimposes a radio-frequency current upon a drive current for the semiconductor laser. An amplitude of the radio-frequency current is set at a value, which causes the semiconductor laser to oscillate in a multiple longitudinal mode, when the drive current for the semiconductor laser falls within a range such that an optical output power yielding a recorded optical density of not higher than approximately 2.0 may be obtained. Nonuniformity in image density is thereby prevented from occurring in the recorded image, and the cost of the apparatus is prevented from becoming markedly high due to countermeasures for nonuniformity in image density.
