Abstract: A variable attenuator for controlling scanning beam intensity having a twisted nematic liquid crystal for rotating the beam, a polarization analyzer for detecting the degree of alteration in the polarization of the beam by the crystal comprising a polarizing beam splitting plate separating the beam into primary and secondary beams, a photocell providing a signal reflecting the intensity of the secondary beam, a control for adjusting power to the crystal in response to the signal, a glass plate at an angle of incidence equal to but opposite from that of the beam splitting plate for correcting aberrations to the primary beam, and an anti-reflective coating on the optical surfaces of the crystal.In a second embodiment, the plates are replaced by a polarizing cube. In a third embodiment, to obviate fluctuations in the attenuator output, the glass plate instead serves as the source of the beam component to the photocell.

Abstract: A holographic display includes "segmented" images configured as if positioned in separate viewing "cells" corresponding spatially to preselected subareas of a desired display area with invisible segmenting cell sides. In one embodiment, a polarized conjugate reference light source projects the segmented hologram images form a light-transmissive recording medium into the display area, a multi-element nematic 90.degree. twisted shutter assembly changes the polarization of light emanating from subareas corresponding to the images to be blocked while keeping unchanged the polarization of the segmented images to be displayed, and a sheet polarizer positioned between the multi-element shutter and the viewer blocks from view images from those subareas which the polarization direction has been changed by the multi-element shutter. In other embodiments, light-reflective recording mediums and multi-element nematic shutters having an appropriate guest-host dyes are used. Constantly viewable unsegmented holographic images recorded in the same recording medium as the segmented images or on a separate recording medium can be multiplexed into the display area using a conjugate light source of a different frequency or having a different polarization condition (e.g., unpolarized) from the conjugate light source used to project the segmented images to be selectively displayed/blocked.

Abstract: A voltage sensing device having a liquid crystal cell electrically connected to a charged surface and having a light transmissivity varying with applied voltage. A light source is directed through the liquid crystal cell, and a light detector, detects changes in the intensity of light directed through the cell and providing an output indicative of variations in voltage on the charged surface. Polarizers, which polarize light from the light source directed through the liquid crystal cell, and analyze light exiting the cell, convert electro-optically induced phase changes into intensity changes. A saturation level biasing voltage is periodically applied to the liquid crystal cell to set the cell to a reference level, clearing the cell of transient polarization effects. A second reference liquid crystal cell may be provided, electrically coupled to a reference voltage. Signals from the charged surface derived by the liquid crystal cell connected to the surface are compared with reference signals derived by the reference cell prior to output of the signal to eliminate a time-based drift component from the output.

Abstract: An aperture plate for a print head of a printer can include a first layer having a first emissivity which is covered by a second layer having a second emissivity which is less than the first emissivity. In an embodiment, the second layer can be etched at nozzle locations to form openings in the second layer which have widths/areas greater than widths/areas of nozzles formed in the first layer. In another embodiment, the second layer can have a smaller thickness at the nozzle locations and a larger thickness away from the nozzle locations. Forming the openings in the second layer which are larger than the nozzles, or forming the second layer thinner at the nozzle locations prior to forming the nozzles, can provide a well-formed nozzle and an aperture plate having a low emissivity.

Abstract: A printhead for printing ink includes a particulate filter manufactured from a polymer sheet such as a polyimide sheet. Filter openings within the particulate filter can be formed using a mask and a laser beam to ablate exposed portions of the polymer sheet. Embodiments of the present teachings can result in the formation smaller filter openings at a smaller pitch within the polymer sheet than, for example, stainless steel particulate filters, and thus more openings which cover a larger percentage of the filter surface for a given filter size, which can result in a reduction of fluid pressure within the printhead. Thus smaller filter openings for improved filtering of smaller particulates can be formed while maintaining a sufficient ink flow at a sufficiently low pressure within the printhead during operation.
