摘要： An ink sensing system for a vector plotter in which a pen is adapted to be raised and lowered from a drawing media surface along a system axis. An optical detection system is provided which has a focal point on the system axis and below the media surface when the pen is in its lowered position and at the media surface when the pen is in its raised position. The optical detection system includes a source of illumination and a detector system to determine the degree of reflectance from the media surface to indicate the presence or absence of ink on the media surface. In a particular embodiment the optical detection system is moveable and the movement of the optical detection system is coupled to the movement of the pen. Furthermore, the focal point of the optical detection system coincides substantially with the last point of contact of the pen with the media surface when the pen is in the raised position.

摘要： A low loss photoplotter imaging system includes a light source having an array of light emitting diodes. A plurality of fiber optic coupling elements are coupled to the LED array and converge to produce a compact high density light source. An aperture plate defining a plurality imaging apertures is interposed between the light source and the medium and is driven by an electric motor to interchange the aperture operative upon the imaging beam. A power zoom lens is utilized to direct and focus the imaging beam upon a photosensitive having a magnification determined in part by the magnification of the zoom lens and close-up lens.

摘要： A bistable storage target for use with a cathode ray storage tube is provided with electrode members forming an interdigitated electrode means. Electrode members connected to one bus bar are provided with collector electrode means which extend through a storage dielectric covering the electrode means for collecting secondary electrons emitted from written areas of the storage dielectric. Electrode members connected to another bus bar are isolated from the first bus bar electrode members and they are raised to a predetermined positive voltage subsequent to the flood gun means being turned off, the writing gun is turned on and the electron beam is directed to a selected area of the target thereby erasing the stored written information thereon.
