Abstract: An apparatus and a method for scanning a surface of an article such as a wooden piece transported along a travel path axis, are capable of generating two complementary color image frames representing the surface of the article in an efficient way. While the sensing field of an imaging sensor is directed transversely toward the travel path axis, a first linear-shaped light beam characterized by a first wavelength is directed toward the scanning zone to form a first reflected line onto the article surface. A second linear-shaped light beam characterized by a second wavelength is directed toward the scanning zone to form a second reflected line onto the article surface. The first and second light sources are activated alternately according to a predetermined frequency, so that the imaging sensor is caused to capture alternately the first and second reflected lines to produce interlaced sequences of reflected intensity image data, which are then separated to generate two complementary color image frames representing the surface of the article.

Abstract: 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.

Abstract: Apparatus and method for inspecting surface quality of a moving sheet of metal illuminates a surface of the moving sheet by the use of at least two lamps. The region which is illuminated by the lamps is inspected by a sensing device. The angle of incidence for the light beams from the lamps are from the near and dark fields. The sensing device picks up highlighted or brightened portions of the sheet due to surface irregularities. By use of a multiplicity of lamps and a single sensing device, such as a video recorder, an inexpensive yet very sensitive system is provided for detecting irregularities in the surface of the moving sheet. The system may be observed by an operator to determine locations of irregularities and as well the system may be adapted to document locations on the moving sheet where the irregularities occur.
