摘要： PURPOSE:To obtain a reproduced image to a reflecting object and a reproduction Fourier transformation image generating optical system by providing a function which converts spatially the polarization, the phase and the intensity of the light made incident on the reflecting object. CONSTITUTION:The light beams 12 radiated from each microlens of a microlens array 11 are collimated by a 1st large diameter lens 13 and overlapped spatially with each other at a rear focal position of the lens 13. An incoherent image 16 is formed on a reflecting surface 14B of a reflecting optical modulator 14 set at the rear focal position of the lens 13 via a 2nd large diameter lens 15. Under such conditions, the image information is displayed on a reflecting surface 14A in accordance with the light intensity and the coherent light reflected on the surface 14A is modulated by the image information via special function provided. Thus it is possible to obtain a simple coherent parallel processing optical system which has high practical properties and high performance.

摘要： PURPOSE:To obtain many Fourier transformation patterns and real images on the same plane of the same optical system simultaneously by using a lens array constituted of microlenses having >=2 kinds of focal length. CONSTITUTION:A 1st microlens array 1, a 1st lens 2, a transmission body 4, a 2nd lens 5, and a 2nd microlens array 7 are arraied in this order in the presence of coherent lighting. Respective microlenses 1A and 1B of the 1st microlens array 1 have their lens diameters determined so that >=2 pieces of luminous flux projected from those microlenses are transmitted, the transmission body 4 is arranged in an area lighted by >=2 pieces of luminous flux, and a 2nd lens 5 has such a lens diameter that >=2 pieces of luminous flux are transmitted. Further, the 1st microlens array 1 is constituted of microlenses having >=2 different kinds of focal length. Consequently, many Fourier transformed patterns and real images of an input image are obtained on the same plane and two processes which differ in character can be performed in parallel.

摘要： PURPOSE:To allow the image of a light ray passing fine lenses to arrive at the same position even if focusing lens in which its spherical aberration remains is employed by setting the focal distances of the fine lenses to different values according to the positions. CONSTITUTION:Since the focal distances of fine lenses of a fine lens array 3 are so set that the values are different as to correct the spherical aberrations thereof, images formed through the lenses near a center can be obtained on the same focusing surface 5 as that of the image formed through the fine lenses on its periphery. Here, the focal distance near the axis of the focusing lens is f, the focal distance near the position isolated at h from the center of the pupil of the focusing lens is f2 , as the focal distance of a fine lens L disposed near the center of the focusing lens, the surface of an article is disposed on the focal point in front of the fine lens, and the focusing surface is disposed at a position isolated by the f from the pupil of the focusing lens 4. Then, in order to maintain the article face position and the image face position always in a focusing relationship irrespective of the position (h) from the optical axis of the fine lens, the focal distance f of the fine lens disposed at the position (h) is set to the following value. f1 =1/[1/f +1/f -1/f2 ].

摘要： PURPOSE:To perform high grade printing by setting the lens diameters of respective fine lenses to different values to equalize the brightness per a unit area on a photosensitive surface of each original picture pattern. CONSTITUTION:The lens diameters of the fine lenses 3A constituting a lens array 3 are respectively different and the lens diameter of each of the fine lenses 3A present in the vicinity of the center of the lens array 3 is set so as to become smaller than that of each of the outside fine lenses. The set values of the respective lens diameters are determined on the basis of the diameter of a photosensitive drum, the angle of inclination of main beam and spec of each part so as to make the luminosity of each image constant. The lens array 3 is constituted by arranging and fixing the fine lenses 3A on the same plane unidimensionally or two-dimensionally at appropriate intervals and a flat plate microlens, wherein a large number of almost semispherical fine lens parts gradually reduced in refractivity from the center toward the outside are integrally formed to a transparent substrate composed of glass or plastic by diffusing a substance increasing the refractivity of the substrate from a large number of the points on the surface of the substrate, is pref. By this method, the character corresponding to each light source can be formed into an image in the same photosensitive quantity.

摘要： PURPOSE:To uniform the quantities of exposure to images corresponding to respective light sources by providing a shutter which switches to pass and cut off light between a 2nd lens and an image formation surface, and varying the opening time of this shutter by transmission patterns. CONSTITUTION:The shutter 11 which is provided between the 2nd lens 4 and a photosensitive drum 5A as the image formation surface may be, for example, either a mechanical shutter or a liquid crystal shutter. In this case, character data is decoded by a decoder 6 and passed through an XY address generator 7 to turn on only a specific gate of a matrix switch 8, thereby supplying a current to only the LED corresponding to it. The decoder 6, on the other hand, accesses a ROM 9 where such a value that the quantities of exposure by the respective light sources become uniform is stored and the opening time of the shutter 11 is controlled through a driver 10 according to the set value. Consequently, an irregularity in the quantity of exposure to images corresponding to the respective light sources is eliminated to enable printing of high uniform quality.

摘要： PURPOSE:To obtain an arbitrary character in a character pattern group at the same position on an imaging plane, by a construction wherein an object plane of an imaging optical system comprising a first lens system and a second lens system is located on a plane opposed to a lens array forming plane of a transparent substrate. CONSTITUTION:A character mask 3 is illuminated by illumination 4, and light transmitted through a character pattern 3 is led through a minute lens array 2 and a projection lens 5 to form an image 7 of the character pattern on an imaging plane 6. All of character patterns 3 located at positions corresponding respectively to minute lenses 2 are located at the position of an object plane of an imaging lens system comprising the minute lenses 2 and the projection lens 5, so that the imaging position on the imaging plane 6 is the same for all of the character patterns 3. Therefore, by turning ON only a specified position of a liquid-crystal shutter 8 to lead only the light transmitted through a specified character in the group of the character patterns 3, it is possible to obtain an arbitrary character in the group of the character patterns 3 at the same position on the imaging plane 6.

摘要： PROBLEM TO BE SOLVED: To provide an illumination optical device whose light quantity is very large and whose illuminance irregularity is small in using a light emitting element array such as an LED array as a light source, and to provide a projection type display device using the same.
SOLUTION: In the illumination optical device 10, the surface to be irradiated 30 being the incident surface of a liquid crystal panel 80 is irradiated with emitted light from the respective LEDs 21 of the LED array 20 through two microlens arrays 50 and 60 and a condenser lens 70. An LED array surface 22 and the principal surface of the microlens array 60 have nearly conjugate relation, and the principal surface of the microlens array 50 and the surface to be irradiated 30 have conjugate relation. The LED array surface 22 and the surface to be irradiated 30 do not have conjugate relation. By adopting an optical system where the LED array surface 22 and the surface to be irradiated 30 do not have conjugate relation, three design parameters on a light quantity transmission rate, the illuminance irregularity and the parallelism of illuminating light are easily optimized with good balance.
