摘要： The invention concerns on-line electro-optical detection of wafer defects by illuminating a continuously moving wafer with a light pulse from a pulsed laser and imaging the moving wafer onto a focal plane assembly formed as a continuous surface of photo-detectors at the focal plane of the optical imaging system. The laser pulses are of duration significantly shorter than the pixel dwell time, such that there is effectively no image smear during the wafer motion. A fiber optical illumination delivery system, which reduces the effects of source coherence, is described. Other aspects of the system include a system for compensating for variations in the pulse energy of a Q-switched laser output, methods for auto- focusing of the wafer imaging system, and methods for removal of repetitive features of the image by means of Fourier plane filtering, to enable easier detection of wafer defects.

摘要： A fiber optical illumination delivery system, which is effective in reducing the effects of source coherence. The system preferably utilizes either a single bundle of optical fibers, or serial bundles of optical fibers. In the single bundle embodiment, the differences in optical lengths between different fibers of the bundle is preferably made to be equal to even less than the coherence length of the source illumination. In the serial bundle embodiment, the fibers in the other bundle are arranged as groups of fibers of the same length, and it is the difference in lengths of these groups which is made equal to, or even more preferably, less than the overall difference in length between the shortest and the longest fibers in the other bundle. Both of these fiber systems enable construction of illumination systems delivering a higher level of illumination, but without greatly affecting the coherence breaking abilities of the system, thus enabling a generally more applicable system to be constructed.
摘要翻译：光纤照明传输系统，可有效减少源相干效应。该系统优选地利用单束光纤或串联光纤束。在单束实施例中，束的不同光纤之间的光学长度的差优选地被制成等于甚至小于源照明的相干长度。在串联束实施方案中，另一束中的纤维被排列成具有相同长度的纤维组，并且这些组的长度差异等于或甚至更优选小于在另一束中最短和最长纤维之间的长度。这两种光纤系统都能够构建照明系统，提供更高水平的照明，但不会对系统的相干断裂能力产生很大影响，因此能够构建通常更适用的系统。

摘要： A tube inspection system includes a guided-wave-transducer mechanism (GWTM) 18 that is associated with a tube 14 that is being inspected. The GWTM can have one ring 16a with N guided-wave transducers (GWTs) distributed thereon, and another ring 16b with M guided-wave transducers (GWTs) distributed thereon. A controller excites mechanical waves by the GWTs of the first ring that propagate in the wall of the tube being inspected and along its axis. The GWTs of the second ring obtain received mechanical waves and convert them to electronic signals. The M electronic signals are processed to provide a measured signal in which a wanted mode is enhanced. N and M are integer numbers equal or greater than two and are not the same. A pressing mechanism 17 is arranged on a transducer cylinder 12 to press the plurality of GWTs toward the tube wall.

摘要： Tube inspections are performed by combining the use of APR technology with GW technology. The reflections measured by both technologies are compared to each other and used to more specifically identify the type and location of a flaw or anomaly that appears in the interior of the tube. Further, embodiments of novel probes to be used in GW technique for inspecting tubes with mechanical waves having bandwidth that is equal to 150 KHz or more are disclosed.
