摘要： The apparatus for normalization of a drilling tool to a work surface includes a light source, a beam splitter, and a screen. The beam splitter directs and the screen receives at least a portion of the light reflected off of the work surface. When the received light is located in a predetermined portion of the screen, then the drilling tool is normal to the work surface. The method for normalization of a drilling tool to a work surface includes positioning the drilling tool proximate the work surface, transmitting light toward the work surface, creating an image of the light that has reflected off of the work surface upon a screen, thereby permitting the orientation of the drilling tool to be adjusted until the image of the reflected light is located in a predetermined portion of the screen that is indicative of proper alignment.

摘要： A laser measuring system for industrial inspection having a laser producing a narrow beam of coherent light which is focused by telescope onto an article. The focused beam of light from the telescope is directed by a scanning means across the article at a known rate. The light reflected from the article is focused by an imaging lens offset from the scanning means onto an optical grating which is provided with alternate transparent and opaque bars. The collected light which passes through the transparent bars of the optical grating is sensed by a photomultiplier detector. A processor which sees the output of the photomultiplier detector determines the time interval between selected points of the output signal of the photomultiplier detector. As the scanning beam moves across the article it causes the laser spot observed by the photomultiplier to traverse the surface faster or slower depending on whether the scanning is proceeding up a portion of the surface of the article or down, respectively. Thus, the reflected light traverses the optical grating at a slower or faster rate and, therefore, the time interval measured by the processor between the selected points on the output of the detector increases as the scanning beam moves up the surface and decreases as the scanning moves down the surface. The processor provides an output directly related to the contour of the article which can be stored and compared with the contour of a master article or prototype.

摘要： An apparatus and method for reading randomly oriented characters having a laser producing a narrow beam of coherent light which is focused by a telescope onto indicia located on a written medium. The focus beam of light is directed by a scanner located intermediate the telescope and the indicia. The scanner directs the beam of light across an area in a known sequence. The light reflected from the written medium having the indicia thereon is received by a photomultiplier detector. The processor which receives the output of the photomultiplier detector determines the observed orientation of the indicia, and the angle between the observed orientation of the indicia and a desired orientation of the indicia. The processor then generates a signal which causes a beam rotating means located between the scanner and the indicia to be rotated to a position so that the indicia are now scanned in the known sequence having the desired orientation with respect to indicia. Characters which are to be read are located adjacent to the indicia. It is desired to scan the characters with the laser beam at the orientation to which the beam rotating means was rotated. The photomultipler detector receives the reflected light from the characters and the written medium as the characters are scanned in the known sequence at the desired orientation.

摘要： A line image or a line signature is optically scanned to generate digital signals for storage in an image matrix. These digital signals represent black and white cells defining the line signature or line image and are initially processed by tracing the image boundary. During the tracing a "thinning" or "peeling off" operation is performed that evaluates black cells in the image matrix for conversion into white cell digital signals. This thinning or peeling off process, also identified as data compression, continues until the line signature or line image is composed of a single cell thickness. The final phase of the data compression operation includes another boundary tracing of the one cell thick image, and connecting a sequence of boundary points defining each black cell to form a string of vectors which represent the signature. The resulting vector catalog comprises a composition of data including a vector starting point and vector directions which are encoded and stored for future retrieval. When a stored line signature or line image is to be retrieved for display, the encoded vector data is recalled from storage to generate on a cathode ray tube the original vector data. This operation is known as data decompression and produces on the cathode ray tube a synthesis of the original line image or line signature. The compression and decompression operations, except thinning or peeling off, are also applicable to textured images or images having grayscale and thickness. Such textured images are first subdivided into binary images, each representing one bit of the grayscale, then the vector boundary encoding process is completed without thinning. The encoded vectors are stored for subsequent retrieval and display.
