摘要： A method and system for compensating for motion blur in optical navigation adds a correction offset to an image navigation value to adjust for varying velocities along a moving web. Reference and comparison images are acquired at different times from a moving web. The instant velocities of the web are determined for the acquisition times for the reference and comparison images, wherein the reference image velocity and the comparison image velocity may not be the same. An optical navigation value is computed representative of the movement of the web from the reference image to the comparison image. Based on the determined velocities and the image acquisition time, the blur distances for the two images can be calculated. A navigation error correction value is computed as one-half the difference between the reference blur distance and the comparison blur distance. A compensated navigation value is computed by adding the error correction value to the computed navigation value to compensate for varying web velocities.

摘要： The invention is directed to methods for direct patterning of silicon. The invention provides the ability to fabricate complex surfaces in silicon with three dimensional features of high resolution and complex detail. The invention is suitable, for example, for use in soft lithography as embodiments of the invention can quickly create a master for use in soft lithography. In an embodiment of the invention, electrochemical etching of silicon, such as a silicon wafer, for example, is conducted while at least a portion of the silicon surface is exposed to an optical pattern. The etching creates porous silicon in the substrate, and removal of the porous silicon layer leaves a three-dimensional structure correlating to the optical pattern.

摘要： The present invention is a method and device for identifying recording media in a printer. The invention utilizes fine structure of the media revealed by illumination from one or more directions to distinguish among different kinds of plain papers, coated papers, such as glossy papers, and transparency films. Multiple light sources at different incidence and/or orientation angles apply light on the test surface, and scattered light is converted into signals and then analyzed. Various metric and analysis techniques can be applied to the signals to determine the media type.

摘要： A print monitoring approach is provided in which sequences of irregular two-dimensional frames of image information are captured at a resolution sufficiently high to enable details of individual droplets to be identified. The approach may be used to monitor individual droplets deposited on a medium, such as a sheet of paper, by an inkjet printhead. An optical detector having an irregular two-dimensional array of closely spaced sensor elements is mounted for movement with the inkjet printhead or other print assembly. A processor is responsive to the image frames from the optical detector to adjust print quality parameters when the physical characteristics of the imaged droplets are detected as being outside of a preselected range of acceptability. The physical characteristics that are resolved may include gyrational information or different droplet position information. Optical dot gain can also be measured.
