Abstract: 一种非金属掺杂物测量装置，包括：在其上放置着断裂表面(h)朝上的样品(S)的工作台(T)；照明装置(7)，其从多个方向用光(L)照射断裂表面(h)；用来检测断裂表面(h)的图像的图像检测装置；用来将所检测图像处理成连续色调图像的连续色调图像处理装置；和用来通过连续色调图像处理结果与阈值之间的比较将连续色调图像二进制化的二进制化装置。由于从多个方向照射断裂表面(h)，通过检测断裂表面(h)的图像所获得的图像没有由断裂表面(h)上的微小不规则性导致的阴影或光学不规则性。因而，所述图像经过连续色调图像处理和二进制化后，样品(S)中的非金属掺杂物就能被从断裂表面(h)中精确地检测到。

Abstract: An NIR spectroscopy fluid analyzing system (1) using a series of LED's (21), each having its own preselected center wavelength, as illumination sources. These wavelengths have overlapping spectral widths, such that the measurement covers a broad spectrum. The LED's (21) illuminate the fluid sample sequentially, and subsequently the transmission absorbance through the sample and the reflectance or scattering from the sample is measured for the wavelength range of each LED. The measurements are performed using photodetectors (24,27,29). The concentrations of component parts of the fluid are expressed in the form of a polynomial, which is a function of the measured transmitted and/or reflected intensities, and of empirical coefficients, which are extracted by prior statistical analysis on measured intensities obtained from a large number of test samples having known concentrations of the component. A novel sample chamber (16), capable of performing optical absorption measurements on a flowing sample of fluid, is described.

Abstract: A device and method for identifying solid and liquid materials use near-infrared transmission spectroscopy combined with multivariate calibration methods for analysis of the spectral data. Near-infrared transmission spectroscopy is employed within either the 700-1100 nm or the 900-1700 nm wavelength range to identify solid or liquid materials and determine whether they match specific known materials. Uses include identifying solid (including powdered) and liquid materials with a fast measurement cycle time of about 2 to 15 seconds and with a method that requires no sample preparation, as well as quantitative analysis to determine the concentration of one or more chemical components in a solid or liquid sample that consists of a mixture of components. A primary application of such analysis includes detection of counterfeit drug tablets, capsules and liquid medications.

Abstract: An impurity measuring device includes a table (T) on which a sample (S) is to be placed with its fracture surface (h) facing up, an illuminating means (7) for irradiating the fracture surface (h) with light (L) from a plurality of directions, an image sensing means for sensing an image of the fracture surface (h) irradiated with the light (L), continuous tone color image processing means for processing the sensed image into a continuous tone color image, and a binarizing means for binarizing the continuous tone color image through comparison between the result of the continuous tone color image processing and a threshold value. As the fracture surface (h) is irradiated with the light (L) from the plurality of directions, the image obtained by sensing the image of the fracture surface (h) is free from shading or optical irregularities caused by minute irregularities on the fracture surface (h). Therefore, impurities in the sample (S) can be accurately detected from the fracture surface (h) by subjecting the image to the continuous tone color image processing and binarization.

Abstract: An engineered lighting system for use in an inspection system is comprised of an array of light emitting diodes. A specimen is brought into the viewing area, and a current pulse is provided to the diodes of the array to selectively flash all or a portion of the diodes of the array. Reflected light from the specimen is sensed and a digitized image is generated therefrom. An illumination level of the digitized image is adjustable, in whole or in part, by varying the effective lighting intensity of one or more of the diodes of the array during a flash period. The digitized image of the specimen is compared to data indicative of acceptability of the specimen, and acceptance or rejection of the specimen is decided on a basis of a comparison therebetween.
