    摘要: A highly uniform infrared illumination source for illuminating a stripe of a moving sensitized web for line scan imaging of imperfections in the coating on the web by a CCD imaging camera. A light integrator having an elongated housing formed with side and end walls defines a linear light integrating cavity having diffusely reflecting interior wall surfaces. An elongated array of infrared LEDs is spaced along the side wall for emitting light into the cavity for integration within the cavity. A longitudinally extending slit is formed in the side wall through which a diffuse, linear light beam exits the elongated slit having a varying longitudinal intensity profile. The intensity of the light emitted by the LEDs is modulated in an intensity pattern that alters the varying longitudinal intensity profile of the linear light beam to provide a desired longitudinal intensity profile of the stripe of diffuse illumination. Preferably, the intensity modulation renders more uniform the longitudinal intensity profile of the linear light beam illuminating the web as viewed by the imaging camera. The desired light intensity profile along the length of the emitted light beam is achieved by clustering the LEDs with LED drive circuits operated at different drive currents as a function of a set point control signal appropriate to the characteristics of the imaging camera and a transmitted light intensity feedback signal to maintain the intensity pattern of the LEDs and the uniform intensity profile as viewed by the imaging camera regardless of the optical density of the web.

    摘要: An optical inspection apparatus detects faults in a material coated on a moving web. Multiple cameras are positioned in an array across the width of the web transverse to the direction of the moving web. Each camera comprises a electronic camera and digital signal processor. An illumination source is preferably positioned to illuminate one side of the web. The camera array is positioned on the opposite side of the web aligned with the illumination source. The cameras in the array image the moving web along colas and collect image data from the web. The image is digitized and processed in real-time by averaging each column of image data to produce a profile of light intensity transmitted across the web width from which faults occurring in the longitudinal direction are detected in a host computer.

    摘要: A spectrometer using a CCD array in the time-delay integration mode is claimed. The spectrometer comprises a CCD having a plurality of charged-coupled devices disposed along a scan dimension which terminates at an output end of the CCD. Each device produces an electronic charge in response to electromagnetic radiation incident thereon. A monochromator, optically aligned with the CCD, has a diffraction grating which generates a plurality of spectral beams from an external source of electromagnetic radiation. The diffraction grating is movably mounted to sequentially scan the plurality of spectral beams. A control unit, coupled to the monochromator, controls the scanning operation of the diffraction grating and determines a scan rate for the spectral beams. The spectral beams are scanned along the scan dimension of the CCD during the scanning operation. A clock source, coupled to the CCD, sequentially shifts the electronic charge from one charge-coupled device to another along the scan dimension of the CCD at a shift rate substantially equal to the scan rate of the spectral beams. A serial shift register, coupled to the output, end of the CCD, accumulates the electronic charge as it is shifted to the output end of the CCD. An output amplifier, coupled to the shift register, produces a video signal from the electronic charge accumulated in the serial shift register. Each produced video signal represents an intensity value for a respective spectral beams.
