摘要： A radiation modifying apparatus comprises a plurality of solid state radiation sources to generate radiation that modifies a first material such as by curing or creating alignment through polarization. The solid state radiation sources can be disposed in an array pattern. Optical concentrators, arranged in a corresponding array pattern, receive radiation from corresponding solid state radiation sources. The concentrated radiation is received by a plurality of optical waveguides, also arranged in a corresponding array pattern. Each optical waveguide includes a first end to receive the radiation and a second end to output the radiation. The radiation modifying apparatus can be utilized for continuous substrate, sheet, piece part, spot curing, and/or 3D radiation-cure processes.

摘要： A computerized rating tool is described that assists a user in efficiently and consistently assigning expert ratings (i.e., labels) to a large collection of training images representing samples of a given product. The rating tool provides mechanisms for visualizing the training images in an intuitive and configurable fashion, including clustering and ordering the training images. In some embodiments, the rating tool provides an easy-to-use interface for exploring multiple types of defects represented in the data and efficiently assigning expert ratings. In other embodiments, the computer automatically assigns ratings (i.e., labels) to the individual clusters containing the large collection of digital images representing the samples. In addition, the computerized tool has capabilities ideal for labeling very large datasets, including the ability to automatically identify and select a most relevant subset of the images for a defect and to automatically propagate labels from this subset to the remaining images without requiring further user interaction.

摘要： An inspection device comprises a camera assembly including an objective lens that captures and collimates light associated with an object being inspected, an image forming lens that forms an image of the object based on the collimated light, and a camera that renders the image. The camera assembly defines a focal point distance from the objective lens that defines a focal point of the camera assembly. The inspection device comprises an optical sensor positioned to detect an actual distance between the objective lens and the object, an actuator that controls positioning of the objective lens to control the actual distance between the objective lens and the object, and a control unit that receives signals from the optical sensor indicative of the actual distance. Control signals from the control unit can control the actuator to adjust the actual distance such that the actual distance substantially equals the focal point distance.

摘要： A method includes providing a substrate having a layer of photosensitive material thereon and a mask having contiguous first, second, and third portions; and sequentially: i) scanning the first portion with a light beam at a first rate and subsequently impinges on the photosensitive material at an exposure zone; ii) fixing the scanning within the second portion; and iii) resuming scanning through the third portion. Throughout the process the substrate moves through the exposure zone. An apparatus for carrying out the process includes a light beam source, a mask mount, a mask stage, a conveyor assembly, and at least one optical element for manipulating the light beam into a rectangular light beam.

摘要： An apparatus that can measure both haze and clarity on a web moving at conventional manufacturing speeds. The apparatus uses an integrating sphere and a novel mirror arrangement. With this arrangement, the invention can utilize a calibration curve created using known samples over the range of measurement desired to convert in real time, and the response of two photo detectors that measure the wide and low angle scattering signals, to deduce the desired optical property values. This approach significantly increases the speed and response of sensor and enables either on-line single point or full web scanning for uniformity measurement and control.

摘要： A system is described for detecting the presence of non-uniformity patterns and providing output indicative of a severity of each type of non-uniformity pattern. The system includes a computerized rating tool that assists a user in efficiently and consistently assigning expert ratings (i.e., labels) to a large collection of training images representing samples of a given product. In addition, the rating software develops a model that allows a computerized inspection system to detect the presence of non-uniformity patterns in a manufactured web material in real time and provide output indicative of a severity level of each pattern on a continuous scale. The system also includes algorithmic and hardware approaches to significantly that increase the throughput of the inspection system.
