Description of the Invention (Technical Field) The present invention relates to a method and device for sensing small impurities in a solid medium such as a large glass. BACKGROUND OF THE INVENTION Sensing small (micron and sub-micron) impurities in glass is always a challenge. The difficulty of measuring various difficulties lies in the depth, sensitivity, and resolution of the rest. The microscope has the ability to sense impurities in the sub-micron range, however, [, [,] has a depth of focus that is not narrow, and the sampling area under high magnification is small. Sensing small impurities is highly desirable. If a microscope is used alone, these _ enable its dictionary to analyze the Dawei ship. Diffusion reflection / scattering has been used to reduce noise. After plotting its location, the impurities can be further identified by microscopy. Nonetheless, the sensing limit for diffuse reflection / diffuse green is 5 microns. In addition, the glass thickness is again limited by the depth to which the microscopy technique focuses narrowly. On the other hand, small particles suspended in a fluid medium such as a liquid or gas can be routinely measured by the scattered light method. The difference between impurities in solid glass and particles suspended in a fluid is important. One difference is that the glassy impurities are quiet.钱 中 ㈣ 常 # is often low, that is, the signal strength is very touching, and it is very difficult to distinguish it from the middle. Noise is crosstalk between surface sensing (surface signal) and depth sensing (internal signal). In addition, the location of impurities in glass is important information. Due to the turbulent nature of suspended particles in the fluid medium, their positions are not scaled. Therefore, the eye-age instrument cannot design the drawing ability with the particle position. Nevertheless, we found that the principle of particle measurement in a suspended fluid medium can be applied to solid glass ^ The paper size is applicable to China 2 ^ 7 ^ 17 542911 V. Description of the invention (X) Impurity measurement. Summary of the invention: The present invention uses two sections of a selected structure. When the glass cube is placed on the platform, the operation begins. When the presence of the block is sensed, the day guard or the start triggers, Ymza_ arrives at the starting position. γ-axis sliding provides precise square secrets in the horizontal γ direction. And the CCD line scan 4-field telecentric device is installed on the second 2-axis slide as a vertical movement. In addition, the camera can be mounted on a micro stage. Scanning every plane in the #square 2 scale will cause the small distance required by its axis to take the focus of all planes. Scanning from plane to plane is performed continuously to a three-degree depth paper cricket machine that covers the entire square, usually placed at an angle to the main light path. The light scattering method for size measurement is mainly based on the irradiated particles (or miscellaneous shells), which is enough as a second light source related to its size. When the Li 1 monochromatic light beam is irradiated with a laser beam as the main light source, the angular distribution of the scattered light intensity from impurities in the range of micrometers to submicrons is a function of the following conditions. The angular distribution of the scattering intensity is a function of the following factors, including scattered light and incident light, the wavelength of the incident light, and the refractive index of the particles relative to the surrounding medium.

In the present invention, the structure is preferably a linear array. In the heterosexual imaging method, the geometry of the two sensor arrays is possible: single-hybrid, a linear sensory array with a design age. TDI is a technology that uses multiple sensor elements to sequentially observe the phase_target in time and allows all images at that point to be added together after an appropriate delay time. Since all the components of Xunli are lakes, and the same readings are irrelevant, it is recognized that the multiple of goodness of view is the square root of the number of elements. The TDI method requires precise synchronization and timing control to get good results. When it comes to images that require the best image, Top provides very high image quality and sensitivity. Calculations and measurements using several laser sources show that the proposed structure is very good and below the laser noise limit. The irradiation of micro-collected particles by a 35mW laser diode with a wavelength of 6_ produces s · greater than 10. At the same time, it is a good lion because it has lower sensitivity than other characteristics of the array obtained by using some TDI arrays. The ultra-low editing performance is enough to produce faster scanning speed and better particle discrimination. In addition, many of these devices have built-in timing generators and timing generators, which quite directly integrate the device into a complete time series. Programmable masking provides additional background identification and control. Preferentially, the sensor is relative to the horizontal axis (this paper size applies to China ^ # 57 cNS) A4Wt ^ (210X297 ^) ε (Please read the precautions on the back before filling this page)

The invention description (+ the path of the main beam) is 90 degrees. Possible lighting sources include toothed bulbs and flash bulbs. Halogen light-correcting light bulbs have non-excellent advantages and are the most commonly used towels with high resolution and rain resolution. In addition, the Qiqi device produces a light source with very high stability as a precise fine system. * Over the proposed system, optimal operation requires the use of a highly collimated small broken mosquito county. This effect can be best achieved by using lasers. The beam axis with low divergence close to the diffraction limit irradiates the impurities across the entire width of the glass block. Collimation, the beam of light shining through the entire scale. In order to obtain the best performance, a laser module with atomic energy control (APG) and good thermal stability is required. We can measure a wide range of solid media. Generally, the solid medium can be any transparent glass, plastic, crystalline material, glass ceramic, etc. In particular, the main challenge is measuring impurities in high-purity fused silica for light mask applications. We need to sense gaseous and refractory impurities in HPFS. -A block of HPFS is approximately 60 inches and the thickness varies from 6 "to 10". For a 6 "size light masking substrate, a 60" diameter dish is first cut to 6 25, χ 6. 25 " Square square of the complete thickness of the dish. The square is polished on three sides and transmitted through the inspection process. The transparency of the sheet varies widely. Obviously, if the medium is translucent, the sensing system will not be very accurate. We found that the media's internal transparency is at least 65%. Preferentially, the transparency should be at least 90%. Figure 1 shows that when the square is scanned in the Z axis, more glass is included in the optical path, which requires small focus adjustments to focus. The function of the position.

The resulting differential focus = permutation can be partially compensated for:!, Points within the entire height X of the entire glass square, cross. Uncompensated focus offset and astigmatism and other aberrations create non-uniform image blur sizes that span the image field and within the height of the cube.

Description of the invention (6) Clear. Void impurities or bubbles are difficult to visually inspect. Nonetheless, these impurities need to be added and lightly timed. The following example will provide very good techniques to sense these internal impurities. Example: The following is an example of an automation system. It can inspect impurities in glass cubes and other defects larger than 1 micron in size. The accuracy of the position where defects can be sensed in the square is ± 300 microns. Edge surface proximity is 125 mil and maximum viewing time is less than 30 minutes. The system contains linear array sensing homozygous to a two-dimensional laser scanning component as a known measurement. A diode laser module with a wavelength of 650nm and a power of 35mW and a modulation (TTL) are used as the wires. Sensing n is placed as a vertical test and is perpendicular to the horizontal axis (for example, perpendicular to the laser beam). -The glass block is moved in the horizontal axis (y direction) to produce a full area image. After mastering, '?, ≫ imaging, the laser is stepped on the vertical axis (z direction) to generate the next image plane. After processing, we will continue to perform all the blocks of the continuous job video.
