摘要： To better address these problems, one or more characteristics are measured from a work piece (28). The measurement information is used to select a preferred predetermined laser processing recipe from a lookup table. The laser processing recipe is then used to process the work piece (28). The lookup table of laser processing recipes can be established from theoretical calculations, from trial an error by an operator, from an automated systematic recipe variation process with post process testing, or from some combination of these or other methods. An automated process can also reduce operator errors and may store measurement values for convenient tracking of work piece characteristics.

摘要： An apparatus and method performing a sequence of processing steps on a load supported by a processing plate. The load can include a single sheet on which a plurality of applications are performed or can include a plurality of panels on which respective applications are performed. For each application, at least one coarse target and at least one panel target are used to adjust the programmed coordinates for that application. After the first application of the load is processed using the coarse and panel targets, coarse and panel targets are located for the second application. Using the alignment provided by these targets, the second application is processed. Each subsequent application is similarly aligned and processed.

摘要： Preferred embodiments of the invention implement techniques for modifying the command trajectory, the architecture of a servomechanism control system, or both, to reduce the servo error during and/or after the command trajectory. An iterative refinement procedure generates for use by the servomechanism control system a corrective input, du, which significantly reduces the error between the desired and actual servomechanism control system outputs. In one embodiment, a uniquely identified plant model is employed in the iterative refinement procedure to compute an approximate gradient that improves the performance and reliability of the refinement procedure. In another embodiment, the actual plant response is used in place of the identified model in the iterative refinement procedure. This is accomplished by time-reversing the stored error signal from a training run, before applying it to the plant to generate an update to the corrective input signal du.

摘要： A method and apparatus to improve image quality in images captured via monochromatic cameras using multi-wavelength lighting. A contrast optimization algorithm determines which particular wavelength among those available is most suitable to maximize contrast. The quality of the image can be further improved through active noise cancellation by determining the lighting schemes that provide maximum and minimum contrast between a target and a background. The elimination of image texture data (i.e., noise) is then accomplished through pixel-by-pixel division of the maximum by the minimum contrast image. Alternatively, images obtained using at least two wavelengths can be algebraically combined for noise reduction. The resulting composite image can be fed into any known target identification algorithm.
摘要翻译：一种改善通过使用多波长照明的单色相机拍摄的图像中的图像质量的方法和装置。对比度优化算法确定可用的那些特定波长最适合于最大化对比度。通过确定在目标和背景之间提供最大和最小对比度的照明方案，可以通过主动噪声消除来进一步改善图像的质量。然后通过最小对比度图像的逐像素划分来完成消除图像纹理数据（即，噪声）。或者，使用至少两个波长获得的图像可以被代数组合用于降噪。所得到的合成图像可以被馈送到任何已知的目标识别算法中。
