AI Technical Summary
It is difficult for existing scanners to achieve high-definition imaging, lens imaging has image distortion problems, and small hole imaging is difficult to take into account both the clarity and the photosensitive intensity due to aperture problems.
Using the principle of small hole imaging, a scanner board composed of glass and small hole plate is formed by irradiating the light strip to form an inverted image, and the image is reversed and spliced on the computer to achieve high-definition imaging.
High-definition, distortion-free scanning images are achieved, reducing manufacturing difficulty and cost, and lower focus alignment requirements.

Abstract
Description
(1) Technical field
[0001] The present invention relates to a scanner plate, in particular to a pinhole imaging scanner plate that performs imaging using the pinhole imaging principle. (2) Background technology
[0002] Pinhole imaging is based on the fact that light propagates in straight lines: when a pinhole can only allow one ray of light to pass through, only one of the straight-line propagating light rays emitted from a point on the light source can pass through the pinhole and illuminate the screen. For each point on the light source, only one ray of light passes through the pinhole and illuminates the corresponding position, forming an image of the light source on the screen. The light emitted by the light source does not converge or diverge, so there is no focus, and therefore no focal length.
[0003] Convex lenses have a converging property. Light from a light source converges to a single point through a convex lens, so only that single point is clearly visible after the lens forms an image. Furthermore, the curvature of the lens during manufacturing isn't always strictly consistent with theoretical values, which can cause irreparable distortion in the image.
[0004] In pinhole imaging, only the distance between the object and the pinhole and the aperture affect image clarity. High-quality scanners require extremely high image clarity, and lens-based imaging no longer meets the clarity requirements of modern high-end scanners. Pinhole imaging is limited in popularity because too large an aperture reduces clarity, while too small an aperture reduces light sensitivity. Therefore, designing a pinhole imaging scanner plate with a compound eye-like structure is feasible.
[0005] Therefore, it is necessary to design a high-definition pinhole imaging scanner plate that utilizes the pinhole imaging principle to perform imaging. (3) Summary of the invention
[0006] The present invention is to design a high-definition pinhole imaging scanner plate which uses the pinhole imaging principle to perform imaging.
[0007] The objectives of the present invention are achieved as follows: the present invention comprises a scanning piece, a glass body 1, a light strip, a pinhole plate, a glass body 2, light, a photoreceptor, a circuit board, a fixing ring, and a pinhole; a photoreceptor is mounted on the circuit board, a glass body 2 is mounted on the photoreceptor, and then a pinhole plate is mounted on the glass body 2, a light strip is inlaid on the pinhole plate, and the glass body 1 is mounted on the pinhole plate; the scanning piece is mounted on the glass body 1; the glass body 1 and the glass body 2 are high-transmittance cubes painted black on all four sides; a pinhole imaging scanner plate is formed by adding a fixing ring to a single array of pinhole imaging scanner plates.
[0008] The image on the scan is displayed by the illumination of the light strip, and this image is projected onto the photoreceptor through pinhole imaging to form an inverted image; by sending each image to the computer for inverted splicing processing, a high-definition, distortion-free scanned image can be obtained. (IV) Description of the accompanying drawings
[0009] The specific structure of the present invention is given by the following embodiments and the accompanying drawings:
[0010] Attachment Figure 1 This is a schematic diagram of the pinhole imaging scanner plate of the present invention. Figure 2 Attached is a single isometric view of the pinhole imaging scanner plate of the present invention. Figure 3 It is an isometric view of the pinhole imaging scanner plate of the present invention.
[0011] Among them, (1) scanning part, (2) glass body 1, (3) light strip, (4) pinhole plate, (5) glass body 2, (6) light, (7) photoreceptor, (8) circuit board, (9) fixing ring, (41) pinhole.
[0012] Refer to the attached Figure 1 A photosensitive body (7) is mounted on the circuit board (8), a glass body 2 (5) is mounted on the photosensitive body (7), a pinhole plate (4) is mounted on the glass body 2 (5), a light strip (3) is mounted on the pinhole plate (4), and a glass body 1 (2) is mounted on the pinhole plate (4). The scanned part (1) is mounted on the glass body 1 (2). The glass body 1 (2) and the glass body 2 (5) are high-transmittance cubes with four sides painted black.
[0013] The pinhole imaging scanner plate is formed by adding a fixing ring (9) to the pinhole imaging scanner plate. Figure 3 This is the case of an array with 5 rows and 5 columns, and the specific number of rows and columns depends on needs. (V) Specific implementation methods
[0014] According to the attached Figure 3 As shown, the pinhole imaging scanner plate of the present invention is mounted on a circuit board (8), and a fixing ring (9) is installed to assemble the pinhole imaging scanner plate of the present invention.
[0015] Refer to the attached Figure 1 , Attachment Figure 3 ; The working process of the present invention is as follows:
[0016] The image on the scanned part (1) is displayed by the illumination of the light strip (3). According to the pinhole imaging principle, this image will be projected onto the photosensitive body (7), forming an inverted image of the original image. Since the glass body is a cube, compared with a strictly curved surface, the two light-transmitting surfaces can be easily highly parallel, and the glass material can be easily made uniform and transparent. In this way, the image distortion rate of this invention will be significantly lower than that of lens imaging. By sending each single image to a computer for reverse splicing processing, a high-definition, distortion-free image of the scanned part (1) can be obtained.
[0017] The present invention has the following features: 1. The scanner plate is composed of a glass body, a pinhole plate, etc., making it easy to manufacture and low-cost. 2. There is no focal length, and the focus has low requirements on the placement of the scanned object. 3. Theoretically, the clarity can be infinitely high.
