    Abstract: A pattern detection method and apparatus thereof for inspecting with high resolution a micro fine defect of a pattern on an inspected object and a semiconductor substrate manufacturing method and system for manufacturing semiconductor substrates such as semiconductor wafers with a high yield. A micro fine pattern on the inspected object is inspected by irradiating an annular-looped illumination through an objective lens onto a wafer mounted on a stage, the wafer having micro fine patterns thereon. The illumination light may be circularly or elliptically polarized and controlled according to an image detected on the pupil of the objective lens and image signals are obtained by detecting a reflected light from the wafer. The image signals are compared with reference image signals and a part of the pattern showing inconsistency is detected as a defect so that simultaneously, a micro fine defect or defects on the micro fine pattern are detected with high resolution. Further, process conditions of a manufacturing line are controlled by analyzing a cause of defect and a factor of defect which occurs on the pattern.

    Abstract: An apparatus and method is provided for identifying a diffusely-reflecting material, such as a textile fabric. A light source transmits radiation onto the unknown material, and a detector receives radiation diffusely reflected by the unknown material, and generates signals indicative of diffuse-reflection characteristics of the unknown material. A processor is coupled to the detector, and includes diffuse-reflection data on a plurality of reference materials. The processor compares the diffuse-reflection characteristics of the unknown material based on the signals of the detector to the reference data, and by a process of elimination, identifies the unknown material.

    Abstract: Systems and methods for measuring a target in a sample, the target being capable of generating an emitted light in response to an excitation light. In an example system, an excitation light source generates the excitation light along an excitation optical path. An attenuation filter arrangement selectively adds an attenuation filter to the excitation optical path. The attenuation filter attenuates the excitation light by a corresponding attenuation factor. The excitation light exits the attenuation filter arrangement along the excitation optical path to illuminate the sample. A light energy detector receives the emitted light generated in response to the excitation light, and outputs a measured signal level corresponding to an emitted light level. If the light energy detector indicates an overflow, signal measurement is repeated with attenuation filters of increasing attenuation factors until the measured signal level does not overflow.

    Abstract: In an optical property measuring method and an optical property measuring apparatus, a spectral transmittance characteristic of a reference colored layer prepared as a reference is corrected based on a measured spectral reflection characteristic of a colored layer, and the spectral reflection characteristic of the reference colored layer. With this arrangement, information on the measured spectral transmittance characteristic of the colored layer can be obtained with sufficient precision in conformity with a printing condition of a sample to be measured. Thus, colorimetry of a printed color of a fluorescent sample i.e. a colored surface on a fluorescent substrate can be accurately performed by using the corrected spectral transmittance characteristic of the reference colored layer.

    Abstract: A method and apparatus are provided for the determination of carotenoid antioxidants and similar chemical compounds in biological tissue such as living skin. The method and apparatus provide a noninvasive, rapid, accurate, and safe determination of carotenoid levels which in turn can provide diagnostic information of the antioxidant status of tissue. Reflection spectroscopy is used to measure the concentrations of carotenoids and similar substances in tissue. White light is directed upon the area of tissue that is of interest. A small fraction of diffusively scattered light is collected and measured. The tissue is pressured to temporarily squeeze blood out of the measured tissue volume while the reflection spectrum is continuously monitored, displayed, and analyzed in near real time. After an optimal time period of typically 15 seconds, the influence of the dominating hemoglobin and oxyhemoglobin tissue absorptions on the reflection spectra are minimized.
