摘要： An optical sheet to be used as a screen on which an image is projected from an image projector is provided. The optical sheet is produced by joining a plurality of optical sheet members with end surfaces thereof meeting each other as joint surfaces. The optical sheet members are realized with lenticular lens sheets. Each lenticular lens sheet has lenses, which are elongated in a second direction, juxtaposed in a first direction orthogonal to the second direction. The optical properties of the optical sheet members that are slightly undulated vary cyclically in the first direction. And the optical sheet members to be joined are a selected pair of optical sheet members whose undulations are substantially identical to each other or symmetrical to each other with respect to the joint surfaces.

摘要： An image forming system is provided which includes an optical sheet and an image projector. The optical sheet is constructed by joining a plurality of sheet members with adjoining sheet members meeting to form a joint line. The image projector produces an image and projects the image to the optical sheet through a projection optical system. The relative positional relationship between the image projector and optical sheet is such that the optical axis of the projection optical system included in the image projector perpendicularly intersects the joint line in the optical sheet. Thus, reflection or scattering of light at the joint line is minimized.

摘要： Three lines' worth of an image are displayed on a columnar display unit 11 comprising a plurality (for example, three) of one-dimensional display devices; this image light beam is made incident on perpendicular deflection means 14, and using the perpendicular deflection means 14, this image light beam is deflected and scanned at high speed in directions perpendicular to the longitudinal direction of the columnar display unit 11 to obtain a two-dimensional image. A plurality of one-dimensional display devices is used, so that compared with conventional devices in which only a single one-dimensional display device is used, even if the rewrite speed (scanning speed) per one-dimensional display device is slow, good image quality free of flicker can be obtained. By further extending this in a configuration using a plurality of columnar display units, a single image can be divided into a plurality of images and displayed in a row on a screen. In order to prevent seams in this juxtaposed display of a plurality of images from being conspicuous, when overlapping parts are provided in the scanned range of the plurality of images, a correction image capture member 47, correction computation member 48, and correction processing member 49 can be used to correct the brightness of the overlapping parts, enabling display of a single high-resolution, large-screen image.

摘要： A dental color measurement tool disposed opposite an opening portion for capturing light from an artificial tooth to undergo color measurement with a color measurement device includes at least one pair of guide posts having an engaging portion corresponding to an engaging portion on the color measurement device side, and an abutment post disposed between the pair of guide posts and having a pointed convex shape to which the artificial tooth can be mounted. The abutment post has a color measurement reference surface in a color measurement light axis direction as the vicinity of a focus position of the color measurement device in a photographing state. When performing color measurement photographing, the artificial tooth is mounted to the abutment post to position the front thereof at the color measurement reference surface. Thus, the artificial tooth can be stably retained at a suitable position with respect to the color measurement device.
