摘要:
A light for an infrared ray) emitting member or a reflective (or an infrared ray reflective) medium is mounted at a predetermined position on an object upon which an image is projected. The light emitting member or the reflective medium is acquired in the coaxial direction of an image projecting unit by an (infrared ray) image pick-up means and video signals obtained by the (infrared ray) image pick-up means are digitized in an image processing unit, such that a highly luminous point of the light emitting or reflected portion occurs in a binary image. A central value of a primary moment on the binary image including the high luminous point, is calculated in real time, and the calculated data is fed back to an electrically-driven driving portion of the image projecting unit, so that the image may be continually projected at the predetermined position. The electrically-drive turntable automatically controls the image projecting direction including the direction of light. The image projecting apparatus projects the image by automatically tracking the position of the moving light emitting member or the reflective medium. Consequently, the image can be continually projected at the predetermined position, automatically tracking the moving object such as an airship or a balloon, so that it can be available as an effective advertizing medium or news.

An exposure apparatus for transferring a mask pattern to a wafer having a surface photoresist layer. The apparatus is comprised of first and second detectors and a determination unit. The first detector includes a light-emitting system for generating first light to illuminate first marks on the substrate and provides first position data. The second mark position detector includes a light-emitting system for generating second light having a wider wavelength distribution than that of the first light to illuminate second marks on the substrate and provides second position data. Determination unit (EGA operational unit 502 or the like) is provided for determining the position of the substrate as a whole by using both of the first and second position data.

An image display device projects lights emitted from each of two two-dimensionally light emitting type photoelectric devices onto first and second light diffusing bodies, and projects and images transmitted images of the light diffusing bodies onto the retina in the respective eyeballs of the user. The display device includes one light source, a first polarization beam splitter dividing light emitted from the light source into P-polarized light and S-polarized light, and an optical system which leads each of the P-polarized light and S-polarized lights respectively to the two photoelectric devices thereby illuminating the two photoelectric devices. The optical system leads polarized light to each of the two photoelectric devices via a second polarization beam splitter and a λ/4 plate, and leads reflected lights to the relay optical system via the λ/4 plate and the second polarization beam splitter.

An exposure apparatus for exposing a substrate with an exposure light beam passing through a mask comprises a movable stage for moving the substrate, a stage chamber for accommodating the movable stage, a transport system for transporting the substrate into the stage chamber, and a first alignment system for performing positional adjustment for the substrate with respect to the movable stage in the stage chamber. The position of an exposure objective delivered from the transport system into the stage chamber can be subjected to positional adjustment by using the first alignment system. The stage chamber and the movable stage can be assembled to a frame of the exposure apparatus in accordance with the module system. The exposure apparatus includes a second alignment system for performing positional adjustment for the substrate installed on the movable stage at an exposure position.

An intermediate image of an image from the LCD module 142 is deflected by reflection mirrors M1 and M2 via zoom automatic focus control system (g) and then is formed on diffusion glass 131 via relay lens (b) and reflection mirrors M3 and M4. The LCD image is projected on the retina of eyeballs via eyepiece lens 132 by the light flux diffused at an order of ±20 degrees by diffusion glass 131. One side of the eyepiece lens 132 close to the crystal balls 2 has an aspherical shape of a Conic surface and a Conic coefficient of the Conic surface is −1 and less. Thereby the optical system that has a viewing angle of 60 degrees and over and has a small aberration can be obtained.

Constant speed drive of a reticle and a wafer in a relative scanning direction and positioning of the reticle and the wafer are simultaneously performed with high precision by a slit scanning exposure scheme. A reticle side scanning stage for scanning a reticle relative to a slit-like illumination area in the relative scanning direction is placed on a reticle side base. A reticle side fine adjustment stage for moving and rotating the reticle within a two-dimensional plane is placed on the reticle side scanning stage. The reticle is placed on the reticle side fine adjustment stage. Constant speed drive and positioning of the reticle and a wafer are performed by independently controlling the reticle side scanning stage and the reticle side fine adjustment stage.
