| PROBLEM TO BE SOLVED: To form a wide image having high resolution from an image provided by the array of a narrow space light modulator available at present. SOLUTION: Two vertically stacked images generated by one or two space light modulators 12 are horizontally aligned through a light wave guide 10. The light wave guide 10 has a channel separator 10a feeding both images along different optical paths. A piar of alignment reflectors 10b, 10c on the optical paths shift the images so that at least a part of the image on the first optical path is aligned in contact with at least a part of the image on the second optical path. The channel separator 10a feeds the images to an image plane 15. The channel separator 10a or at least two reflecting surfaces of the alignment reflectors 10b, 10c are applied with optical diopters to change the width or height of the images. | ||||||
| 122 | Light source device with dual reflection mirrors for eliminating lamp shadow | JP19640195 | 1995-08-01 | JPH08138426A | 1996-05-31 | KIN TOUGA |
| PROBLEM TO BE SOLVED: To obtain a device eliminating a lamp shadow by providing a first reflection mirror having an aperture at its center for reflecting light from a lamp disposed at a first focal point of an elliptical reflection mirror, and a second reflection mirror for reflecting the light reflected from the first reflection mirror and passing the light through the center aperture of the first reflection mirror to allow generation of parallel light by a lens. SOLUTION: In this device, an elliptical reflection mirror 2 reflects rays from a metal halide lamp 1 located at a focal point of the mirror 2 to a lens 6 for collimating the rays. A first reflection mirror 3 having an aperture 5 at its center reflects rays from the lamp 1 to a second reflection mirror 4. The second reflection mirror 4 is positioned in front of the lamp 1 and reflects the reflected and condensed rays from the first reflection mirror 3 toward the lens 6 to allow the lens 6 to collimate the rays. A focal point of the rays reflected by the reflection mirror 2 coincides with the focal point of the lens 6 near the aperture 5. An effective area of the reflection mirror 3 and distance between the lamp 1 and the reflection mirror 3 accurately compensate the reduction of a light intensity caused by a lamp shadow. The reflection mirror 4 is set in an accurate position and direction. COPYRIGHT: (C)1996,JPO | ||||||

| PURPOSE:To obtain an optical device which never causes deterioration of an image even when the angle of a roof type combined mirror is not precise, by arranging an image forming lens and the combined mirror so that the optical axis of the lens and the ridge of the mirror shift in position from each other. CONSTITUTION:The image forming lens 11 and roof type combined mirror 12 are arranged so that the optical axis of the lens and the ridge 14 of the mirror 12 shift in position from each other. Consequently, a light beam emitted from any point between points P3 and P4 on an object surface 10 is reflected by one reflecting mirror 12 and then reflected by the other reflecting surface 12b to form an image on an image surface 13. A roof type prism is usable instead of using the roof type combined mirror. | ||||||
