Description

Halogen Adjustable Planar Linear Lighting

The present invention relates to a halogen variable planar linear illumination device for illuminating the image data which is essential when inputting the image data in the optical recognition or three-dimensional stereoscopic image of the next generation computer.

Generally, two types of planar linear laser beams are used to input optical recognition or image data of a three-dimensional stereoscopic image. One is a red laser beam (distributed in the wide frequency range of 630nm to 880nm), which is used to recognize the position of the image data and contains a relatively sufficient amount of energy, so that the recognition can be accurately made. Therefore, colors other than red cannot be spectroscopically. The other is white or light orange laser beam that is used to spectroscopically recognize the color of the image data. The laser beam can spectrograph several colors, but the amount of energy is relatively small so that the pixel It is not suitable for perception. The high energy white laser beam is very economical at very high cost and is used in special laboratories. Complementary use of these two types of laser beams to search and colorize image data at the same location and extract the image data of three-dimensional stereoscopic images by combining them requires many difficult and difficult techniques in this process. . These requirements are costly to manufacture.

In the conventional optical recognition equipment or three-dimensional stereoscopic image input equipment of the conventionally used conventionally, a special planar linear beam that emits light to extract the position coordinate data for the image data of the target point to be recognized and The production cost is high due to various difficult and difficult technologies that occur in the process of searching and coloring the data at the same location by using special planar linear rays that emit light to extract color data for image data. There was a problem that the production process is difficult.

The present invention has been made in view of the above-mentioned problems, and the like, and natural light (processed light rays) originated from the light emitting portion is re-collected in a straight line in the cylindrical lens and the width of the light beam is adjusted in the linear aperture, and then the visible light band Since light beams from to near infrared rays are projected in a planar straight line, it is difficult to provide a lighting device that can extract position coordinate data and color data of image data of a target point to be recognized in one ray. The aim is to make it easy and simple to build difficult technologies and to reduce production costs in the production of optical recognition equipment and three-dimensional stereoscopic image input equipment of next generation computers.

Referring to the configuration and operation of the present invention for achieving the above object in detail based on the accompanying drawings as follows.

Halogen variable planar linear illumination device (Halogen Variable Line-Emitter) according to the present invention is a power supply 1 for supplying power of different intensity, and a cylindrical tungsten halogen lamp (2a) to emit light by the power supply (1) Or a light emitting portion 2 consisting of two concave mirror reflective tungsten halogen lamps 2b and 2c, and a light beam focused by a light converging reflector of the light emitting portion 2; A heat shield consisting of an optical plane reflection mirror portion 3 for evenly transmitting light, an optical color glass plate 4a in which light green and blue are combined to block excessive heat rays, and a small fan 4b for cooling the heat ( 4) and a cylindrical lens part 5 for condensing the light beam transmitted from the light emitting part 2 with high density and producing a straight and straight light beam, and a linear light beam made from the cylindrical lens part 5. Straight aperture 6 for adjusting the width of the light beam according to the application, lens 7a and projected lens 7b for accurately illuminating the planar straight light beam passing through the aperture 6 to a target point far away. Characterized in that consisting of the project portion (7) consisting of.

According to the above configuration, the light emitting unit 2 should emit light close to natural light, but two methods are used depending on the use of the light beam. First, in optical recognition, the cylindrical tungsten halogen lamp 2a or the concave mirror reflective tungsten halogen lamp 2c is used to recognize positional data or any shape. The wide band of tungsten light emitting sources ranges from visible light to infrared light, and the closer to infrared light, the more energy is contained. The light-receiving elements of commonly used optical cognitive equipment react in the near infrared rays containing sufficient energy. Secondly, a blue concave mirror reflective tungsten halogen lamp (2b) and a concave mirror reflective tungsten halogen lamp (2c) to extract color data of image data of a target point to be recognized in a three-dimensional stereoscopic image input device. ) Is used to complement each other at the same time to reinforce the weak energy in the light frequency 455nm-577nm region seen in the tungsten light source. The light rays emitted from the light emitting source proceed to the optical plane reflection mirror 3.

In the optical plane reflecting mirror portion 3, the light rays emitted from the light emitting portion 2 are transferred to the cylindrical lens 5 for condensing linearly. The light beams collected by the reflective light collecting unit of the light emitting unit 2 itself are reflected by the elongated rectangular optical plane reflecting mirror unit 3 and are corrected to some extent by the linear light beams, and these light beams proceed in parallel to be incident on the cylindrical lens 5. do. When calibrating with more sophisticated light beams, bundles of light-incident areas of optical glass fibers are placed at the light-collecting points of the light emitting units, and optical fiber bundles of the light-emitting areas are arranged in a straight line. When extracting the color data for the image data, when the blue concave mirror reflective tungsten halogen lamp (2b) and the concave mirror reflective tungsten halogen lamp (2c) are complementary to each other and the light is staggered, the optical reflection mirror ( In 3) the mixed light is reflected (FIG. 5). Using an optical glass fiber (optical fiber) (FIG. 6), as shown in the bundle (3a) of specially rearranged bundles of optical fibers that are interlaced with each other to maximize the mixing of complementary light. The selected light beam passes through the heat shield 4.

In the heat shield 4, an optical colored glass plate 4a in which pale green and blue is combined to protect the cylindrical lens from the high thermal energy of the light beam propagating from the light emitting unit 2 is installed to form a heat shield wall and heat. Install a small fan (4b) to cool the hot air circulates.

In the cylindrical lens 5, the light beams which proceed in parallel and receive light are focused again. The spherical lens is condensed at a high density at a single point of focus f as shown in FIG. The cross section of the largest diameter of the sphere may be simulated as shown in FIG. 7, and the circle of the cross sections may be densely arranged as shown in FIG. 8 to form a cylindrical lens. The focal points f of the cross sections are also arranged in a line. The high-density focused single-point focal point f in a sphere is arranged into a focal point f, a focal point f1, a focal point f3, a focal point f4, a focal point f5, a focal point fn-1, and a focal point fn.

In the linear diaphragm 6, the width is adjusted according to the use of the light beams linearly collected by the cylindrical lens 5. In adjusting the width of the linear diaphragm 6, the center line of the light beam projected on the target does not vary, so both wings of the linear diaphragm must be widened or narrowed about the center reference line. The principle uses the proposition that, in parallelograms, the top and bottom sides are always parallel, even if the height of the quadrilateral is increased or decreased. In the parallelogram, two sides of the same size rectangle are used instead of the top and bottom sides, and the hypotenuse uses rods of the same size (Fig. 7).

Looking at (Fig. 10) to (Fig. 12),

In (parallel quadrangle i1, i3, j3, j1) in FIG. 10,

If we look at the inside small (parallel quadrilateral i1, i2, j2, j1) and (parallel quadrilateral i2, i3, j3, j2),

Line segment

i1 i2 = i2 i3,

j1 j2 = j2 j3,

i1 i2 = j1 j2, i1 j1 = i2 j2 = i3 j3,

In (parallel quadrilateral i1 i3 j3 j1),

Line segment

i1 j1 = i3 j3,

i1 i3 = j1 j3,

i1 i3 = [point (i1, i2, i3)],

Since j1 j3 = [point (j1, j2, j3)]

(I1⇔i3) in [point (i1, i2, i3)] is centered on j2

(J1⇔j3) in [point (j1, j2, j3)] is point symmetrical with respect to j2.

In (parallel quadrilateral i1, i3, j3, j1),

[(i1⇔j3), (i3⇔j1), (i1 j1⇔i3 j3)] are point symmetrical movements with respect to the center point p of i2, j2,

[(Parallel quadrilateral i1, j1, i2, j2) ⇔ (parallel quadrilateral i2, j2, i3, j3)] also makes point symmetrical movement with respect to the center point p of i2, j2,

Therefore, [(parallel quadrilateral i1, i2, j2, j1) ⇔ (parallel quadrilateral i2, i3, j3, j2)] is equidistant with each other based on the center line (line segment i2, j2).

As a result, both blades are equally widened and narrowed from the center reference line, so that the width of both blades of the aperture is adjusted and the width of the linear beam is adjusted.

When the aperture is made as shown in FIG. 11, the spring pulls i1 to the auxiliary wall to open the aperture and the bolt stops opening, or when the bolt is tightened, the aperture is closed. Therefore, tightening the bolt will close the iris and loosen the bolt to open the iris. In addition, since the direction of the spring force and the force in the advancing direction due to the rotation of the bolts are relatively opposite to each other, both wings can always be fixed stably. The width (thickness) of the halogen linear light beam is conveniently adjusted according to the use purpose by the width adjustment of the aperture, and the process proceeds to the project lens unit 7.

The project lens unit 7 adjusts the length and distance of the light beam so as to project the processed straight light beam to the target accurately. The type of lens also varies depending on the type of target to be projected and its use. The fixed attachment part of the lens should be manufactured to be able to exchange various lenses, and the lens replacement aperture should be of international common size. The halogen variable planar linear light thus obtained is In M It was possible to precisely adjust up to M, and by producing tungsten light emitting sources with precise planar straight rays, planar linear rays in the visible and near infrared bands were obtained.

As described above, in the halogen variable planar linear illuminator according to the present invention, the natural light source (light beam processed by two kinds of concave mirror reflective tungsten halogen lamps) originated from the light emitting portion is recondensed in a straight line in a cylindrical lens and the aperture is stopped. Since the width of the beam is adjusted precisely and precisely, and then the beam from the visible band to the near infrared band is transmitted in a planar straight line, the position coordinate data and the color data for the image data of the target point to be recognized By providing a lighting device that can be extracted from the light beam, it is possible to easily and simply build up the existing difficult and difficult technologies, and to reduce the production cost in the production of optical recognition equipment or 3D stereoscopic image input equipment of the next generation computer. Has the effect of maximizing.
