Abstract: Systems and methods for calibrating a solid-imaging system (10) are disclosed. A calibration plate (110) having a non-scattering surface (140) with a plurality (150) of light-scattering fiducial marks (156) in a periodic array is disposed in the solid-imaging system. The actinic laser beam (26) is scanned over the fiducial marks, and the scattered light (26S) is detected by a detector (130) residing above the calibration plate. A computer control system (30) is configured to control the steering of the light beam and to process the detector signals (SD) so as to measure actual center positions (xA, yA) of the fiducial marks and perform an interpolation that establishes a calibrated relationship between the angular positions of the mirrors and (x,y) locations at the build plane (23). The calibrated relationship is then used to steer the laser beam in forming a three-dimensional object (50).

Abstract: The invention is a passive method to measure the translational speed of a visual scene using the distribution of light intensities. Measuring the speed of translation is useful for control, safety, management of resources, fuel efficiency, and many more application fields. It is however technically challenging because a wide-field translating scene projects on an image plane as a heterogeneous field of apparent speeds. The invention solves this problem by combining two principles: perspective distortion matching over a broad field of view, and temporal filtering variation. In conventional systems, an acquired image is calibrated to obtain linear coordinates. Instead, the invention uses the perspective distortion of the image to sample the visual scene at different linear wavelengths over the visual field. The result is a spatial sensitivity map of the visual scene. The obtained signal is then temporally filtered with cutoff frequencies proportional to the spatial sensitivity. The final result is the wide-spectrum computation of the ratio between temporal and linear spatial frequencies, in other words linear speed. The technique is passive because it does not require the emission of a reference signal. This is an advantage over active speed sensors mainly because of reduced power consumption, but it is an enabling factor for other applications. Where it is difficult or impossible using standard device-centered techniques, like on aircrafts or in fluids, the invention enables measuring absolute linear speed. The advantage over non-device-centered techniques like—GPS—is the independence from external infrastructures. The small computational overhead makes it ideal for mobile applications.

Abstract translation: 本发明是使用光强度分布来测量视觉场景的平移速度的被动方法。 衡量翻译速度对于控制，安全，资源管理，燃油效率以及更多的应用领域都是有用的。 然而，技术上具有挑战性，因为广域翻译场景作为视觉速度的异质场投影在图像平面上。 本发明通过组合两个原理来解决这个问题：宽广视野的透视失真匹配和时间滤波变化。 在常规系统中，校准获取的图像以获得线性坐标。 相反，本发明使用图像的透视失真来在视野上以不同的线性波长采样视觉场景。 结果是视觉场景的空间灵敏度图。 然后用与空间灵敏度成比例的截止频率对获得的信号进行时间滤波。 最终的结果是频谱计算时间和线性空间频率之间的比例，换句话说是线速度。 该技术是被动的，因为它不需要发射参考信号。 这主要是因为功耗降低，这是有效的速度传感器的优势，但它是其他应用的一个有利因素。 使用标准的以设备为中心的技术（如飞机或液体）难于或不可能使用本发明，可以测量绝对线速度。 与以非设备为中心的技术（如GPS）相比的优势是与外部基础设施的独立性。 小的计算开销使其成为移动应用的理想选择。

Abstract: There is provided a film measuring device capable of accurately and easily measuring the thickness of a microporous film formed on a battery electrode plate over the entire area of the film. A color CCD sensor 8 shoots the microporous film. A video board 11 converts a color tone of a color image signal obtained by the image pickup into gradation data of respective color components of RGB. After the data conversion, an image processing board 12 extracts line images of the respective color components. A calculator 14 obtains the thickness of the microporous film by referring to pre-measured film thickness reference values corresponding to the gradation data of the green or blue color component, which are stored in a table storage 13 as reference thickness table data, using the gradation data of the line image of the green color component or the blue color component as lookup data.

Abstract: The invention is directed to a method and a kit for calibrating a photoluminescence measurement system, in particular a fluorescence measurement system. The kit includes a number of fluorescence standards i and their corrected and certified fluorescence spectra Ii(λ), whereby the fluorescence standards i are selected, so that their spectrally corrected fluorescence spectra Ii(λ) cover a broad spectral range with high intensity. The standards are characterized by large half-widths FWHMi of their bands of at least 1400 cm−1. According to the method of the invention, partial correction functions Fi(λ) are generated by forming the quotient of the measured fluorescence spectra Ji(λ) and the corresponding corrected fluorescence spectra Ii(λ), which are then combined to form a total correction function F(λ) for a broad spectral range. The combination factors αi are hereby computed by statistical averaging of consecutive partial correction functions Fi(λ) over only a predefined, limited overlap region λi/i+1±ΔλOL about the mutual crossover wavelength λi/i+1.

Abstract: The positions of diffraction gratings used for calibration can be checked easily by arranging marks near the diffraction gratings, the marks indicating the coordinate positions of the diffraction gratings. Dummy patterns including a pattern of cross marks are arranged around the array of the diffraction gratings. Consequently, a uniform diffraction grating pattern is accomplished in which the proximity effect is uniform across the diffraction grating array. Furthermore, cross marks can be disposed adjacent to the diffraction grating array. Therefore, the diffraction gratings can be placed in position and calibrated accurately and easily by using a standard component capable of realizing accurate positioning of the diffraction gratings. Hence, accurate metrology calibration coping with the next generation of semiconductor lithography technology can be accomplished.
