摘要： Printed wiring boards (PWBs) applied to this inspection system are previously formed with marks in prescribed positional relation to wiring patterns. Deviation of PWBs with respect to absolute coordinates of the inspection system is detected by reading the marks. The PWBs are sequentially set one by one on a movable table, to be subjected to image acquisition of the marks and inspected areas. A first PWB is image-acquisited whereby obtained binary image data of the inspected area are stored in a memory unit. Thereafter a second PWB is image-acquisited, and in advance to the image acquisition of its inspected area, relative misregistration of the both PWBs is found by deviation data on respective marks of the first and second PWBs. The binary image data of the first PWB is read from the memory unit on the basis of the binary image data of the second PWB. When the binary image data of the first PWB are read, positional correction, i.e., time base correction is performed on the read data to correspond to pixels of the second PWB under image acquisition on the basis of data on the previously found amount of relative misregistration. The data on corresponding pixels of the both PWBs are compared with each other thereby to inspect difference between the patterns of the PWBs on the basis of the result of the comparison.
摘要翻译：应用于该检查系统的印刷电路板（PWB）预先用与布线图案规定的位置关系的标记形成。通过读取标记来检测PWB相对于检查系统的绝对坐标的偏差。 PWB在可移动台上依次依次设置，对标记和检查区域进行图像采集。第一PWB被图像采集，由此获得的被检查区域的二进制图像数据被存储在存储单元中。此后，第二PWB被图像采集，并且预先对其检查区域进行图像采集，通过第一和第二PWB的相应标记上的偏差数据，发现两个PWB的相对重合。基于第二PWB的二进制图像数据，从存储器单元读取第一PWB的二进制图像数据。当读取第一PWB的二进制图像数据时，基于关于先前发现的相对重合的数量的数据，对读取的数据执行位置校正，即对于与图像采集期间的第二PWB的像素对应的时基校正。将两个PWB的对应像素的数据进行比较，从而根据比较结果来检查PWB的图案之间的差异。

摘要： An improved apparatus for measuring the printed area of a printing plate upon which a printing image is formed, of the type having a movable scanning head provided with longitudinally arranged light sources and plural photosensors arranged in parallel with the light sources. The improvement is composed of a proving sensor device separate from and movable independently of the scanning head which includes at least one light source and photosensor. The proving sensor device provides calibration data for correcting the measurements made by the scanning head. It does this by measuring the intensity of reflected light from a totally dark printing area and a non-printing area from anywhere on the printing plate, and a totally reflective surface and totally absorptive surface, which are preferably located apart from the printing plate. The improvement further includes control means for electronically processing the measurement data produced by both the scanning head and proving sensor device.

摘要： Disclosed herein is an image pickup apparatus for a printed wiring board comprising a solid state image sensor whose light receiving surface is set to be opposed to the surface of the printed wiring board, a main illumination source arranged to satisfy the law of regular reflection on the surface of the printed wiring board with respect to the light receiving surface of the solid state image sensor and a subsidiary illumination source arranged not to satisfy the law of regular reflection with respect to the light receiving surface of the solid state image sensor thereby to supply the light receiving surface with scattering light by strias formed on copper patterns. The amount of regularly reflected light, which is changed depending on the strias formed on the copper patterns, is substantially compensated by the scattering light, so that the amounts of light received by the solid state image sensor relating to the copper patterns are made substantially constant regardless of the radiation pattern of the strias. In addition, the main and subsidiary illumination sources are formed by light emitting diodes thereby to attain technical and economical advantages.

摘要： A method for stabilizing the intensity of a light beam emitted by a light source and deflected by an acoustooptical deflector element which is controlled by a control signal and is arranged in a scanning exposure head, without regard to deflection angles, wherein a detected light beam intensity is compared with a predetermined reference light intensity. The difference between the light beam intensity and the reference light intensity is detected, and wherein the control signal corresponding to the detected difference is controlled by a stored correction signal which is read out of a memory, so that the intensity of the light beam through the acoustooptical deflector element may be maintained at a certain level.
