An apparatus and method for forming vias in one or more layers, comprising one or more beams located in alignment with the layers for forming one or more vias in one or more areas of the layers. A vacuum mechanism is provided for collecting ablated material caused by the directed beams forming the one or more vias, the vacuum mechanism being in fixed alignment with respect to the one or more beams such that the vacuum applies a removal force on the ablated material at the time and location when the one or more vias is being formed.

A method and apparatus for forming vias in one or more layers, comprising providing a vacuum chamber, one or more beams in the vacuum chamber. The array of directed beams located in alignment with a layer for ablating one or more areas of the layer for forming vias. A cold trap is also provided in the vacuum chamber that is in fixed alignment with respect to the one or more beams such that the ablated material condenses upon the cold trap at the time and location when the one or more vias is being formed.

A method of transferring organic material from a donor element to a substrate includes providing a radiation source; and selecting the power of the radiation applied to the donor element by the radiation source to cause the transfer of organic material to the substrate wherein the time that one or more positions of the donor element receives radiation is greater than 1 millisecond.

A method of inspecting an OLED device to locate and characterize defects in the registration of organic material(s) transferred from a donor in swaths in response to heat produced by a multichannel laser print head includes optically inspecting the OLED device after or during manufacture to identify the boundaries between swaths of transferred organic material(s), and determining if the swaths overlap at a seam of the boundary or if there is a gap between swath edges at the seam or if there is an offset between the edges of adjacent swaths.

A method of sensing the pitch or relative location of a lenticular lens on a sheet of transparent lenticular material of the type having a repeating pattern of cylindrical lenses on one side and a flat opposite side, comprising the steps of: forming a beam of light; focusing the beam of light into a spot smaller than the pitch of the cylindrical lenses onto the lenticular material; moving the lenticular material relative to the beam in a direction perpendicular to the axes of the cylindrical lenses to modulate the angle of reflection or refraction of the beam of light; and sensing the position of the modulated beam of light to determine the pitch or relative location of lenticular material to the focused spot.

A film scanner is disclosed including a linear image sensor moveable to a scan position for scanning lines of image frames of an elongated film having a series of edge perforations including a reference perforation for each image frame. The film scanner further includes a rotating film gate for supporting the film in the scan position wherein the rotating film gate includes a rotatable encoder for producing an encoder signal indicative of the position of the film as it passes through the rotating film gate, a film transport mechanism for advancing the film through the rotating gate, a perforation detector mounted relative to the scan line of the image frame located at the scan position for producing hop and weave signals in response to detection of the reference perforation, a sensor transport assembly mounted relative to the rotating film gate and moveable in a weave direction, and including means for mounting the image sensor for movement in the weave direction, and signal processing means responsive to the weave signal for causing the sensor transport assembly to move the linear image sensor in the weave direction to align the linear image sensor with the image frame associated with the reference perforation, and further including means responsive to the hop signal and the encoder signal for producing a start scan signal.

A lenticular image product is formed from a lenticular material having an array of cylindrical lenses and a photographic emulsion coated thereon, by scanning the lenticular material with an intensity modulated first beam of light in a direction parallel to the long axes of the cylindrical lenses to form a latent lenticular image in the photographic emulsion. A second beam of light having a wavelength outside of the range of sensitivity of the photographic emulsion is focused into two distinct spots or a line both with a width smaller than the pitch of the cylindrical lenses onto the lenticular material. The lenticular material is moved through the beam in a direction perpendicular to the axes of the cylindrical lenses to provide a page scan motion of the lenticular material and to modulate the angle of reflection or refraction of the second beam of light. The position of the angularly modulated second beam of light is sensed at two locations along the long axes of the lenticules to generate a skew correction signal to control the alignment of a writing beam to the lenticular material.

An adjustable iris diaphragm assembly (26) in a zoom lens system (16) of a photographic printer (10) is calibrated for each magnification setting by progressively adjusting the aperture opening until a predetermined light intensity is detected by a sensor (36) near a paper plane of the printer and then determining an output voltage of a feedback sensor (88) of the iris diaphragm assembly. A correlation is established among magnification settings of the printer, iris stop settings, and sensor output voltages to enable the printer to accurately set the iris for a desired exposure.
