Abstract:
An imaging optical system includes a plurality of lens optical system rows each including a plurality of lens optical systems arranged in a first direction. The plurality of lens optical system rows are arranged in a second direction perpendicular to the first direction and to an optical axis direction. Each of the plurality of lens optical systems in each of the plurality of lens optical system rows is configured to form an erect equal-magnification image in a cross section perpendicular to the second direction and configured to form an inverted image in a cross section perpendicular to the first direction. In a cross section perpendicular to the optical axis direction,optical axes of the respective plurality of lens optical systems in adjoining ones of the plurality of lens optical system rows are separate from one another in the first direction and being located on a same line.
Abstract:
A surface-emitting laser device configured to emit laser light in a direction perpendicular to a substrate includes a p-side electrode surrounding an emitting area on an emitting surface to emit the laser light; and a transparent dielectric film formed on an outside area outside a center part of the emitting area and within the emitting area to lower a reflectance to be less than that of the center part. The outside area within the emitting area has shape anisotropy in two mutually perpendicular directions.
Abstract:
An image copying apparatus includes a copier (3) for copying an image and an imager (2) which forms charateristics of the (3) image. The imager includes a liquid crystal image forming and storing system (1) for forming in real time characteristics of an image in response to a prescribed input (4) and for temporarily storing those characteristics for a time adequate for the copier (3) to copy the same and a scanning device (42) to scan the image forming and storing device to apply the characteristics thereto. In one embodiment the liquid crystal (5) is operationally nematic liquid crystal (12) encapsulated or contained in a support medium (11) that has a capacitance characteristic, and the scanning device (42) includes a dynamic electrode which applies surface charge to selected areas (24, 25) of the encapsulated liquid crystal/support medium (5) affecting the liquid crystal structural alignment to create the image characteristics. A graphics copying method includes the steps of applying respective prescribed inputs to selected areas (24, 25) of a sheet-like liquid crystal material (5) to cause the liquid crystal material (12) to effect the transmission, scattering or absorption of incident light thereby to form characteristics of an image, and using a copying process copying the characteristics to form a copy of such image.
