Abstract: An adjustable polar blind assembly for window includes a 90-degrees polarization filter, an adjustable shade unit, a 0-degrees polarization filter. The 90-degrees polarization filter, which is positioned adjacent to a window, is mounted offset of the adjustable shade unit. The 0-degrees polarization filter is mounted offset of the adjustable shade unit, opposite of the 90-degrees polarization filter. Moreover, the angles of polarization for the 0-degrees polarization filter and the 90-degrees polarization filter are oriented perpendicular to one another. The adjustable shade unit includes a retractable roller mechanism, a 45-degrees polarization filter, and a transparent filter. The 45-degrees polarization filter that has an angle of polarization of 45 degrees relative to the perpendicularly oriented filters is connected to the retractable roller mechanism by the transparent filter.

Abstract: The present invention relates to a method of displaying an artwork, comprising the steps of: i) providing a complete image, a first substrate, and a second substrate; ii) dividing the complete image into a first image segment and at least one subsequent image segment; iii) imposing the first image segment on the first substrate; iv) imposing the at least one subsequent image segment on the second substrate; and v) positioning the first substrate parallel to the second substrate such that the complete image is revealed with a perception of depth when the first substrate and the second substrate are viewed from a predetermined angle.

Abstract: A completely portable, rugged camera for providing in real time, visual light images of extended objects emitting low energy X-ray and gamma-ray photons. Collimated radiation eminating from extended objects such as internal anatomical organ structures which have absorbed low dosages of radio-active isotopes, are filtered through a visible light shield, converted into visible light photons, and, alternatively magnified or demagnified while spatial orientation is maintained. The visible light photons are subsequently intensified, in one or more cascaded stages, through conversions into electrons, multiplied through micro-channel plate electron multipliers, and reconverted by a phosphor screen to visible light and provide a high spatial resolution visual light image either directly to a viewer or to a device such as an image recorder.

Abstract: An instrument for obtaining quantitative, three-dimensional and tomographic information relating to x-ray and gamma-ray emitting objects and for the orthoscopic viewing of such objects includes a multiple-pinhole aperture plate (22) held spaced from an x-ray or gamma-ray to visible-light converter (24) which is coupled to a visible-light image intensifier (26). The spacing between the aperture plate and the converter is chosen such that the mini-images of an emitting object formed by the pinholes do not substantially overlap as they impinge on the converter. The output of the image intensifier is digitized by a digitizing camera (36) in terms of position and intensity and fed into a digital computer (40,42). The computer may output quantitative information relating to the emitting object directly, such as that relating to tomograms, or provide information in analogue form when coupled with a suitable viewing device (52,54), to give an orthoscopic, three-dimensional image of the object.

Abstract: A multi-pinhole aperture lead screen (22) forms an equal plurality of invisible mini-images having dissimilar perspectives of an x-ray and gamma-ray emitting object (ABC) onto a rear-earth phosphor layer (24) which, in turn, provides visible light mini-images directly into a visbile light image intensifier (26). A viewing screen (34/48) having an equal plurality of dissimilar perspective apertures distributed across its face in a geometric pattern identical to the lead screen, provides a viewer with a real, pseudoscopic image (A'B'C') of the object with full horizontal and vertical parallax. Alternatively, a third screen (34) identical to the viewing screen (48) and spaced apart from a second visible light image intensifier (42), may be positioned between the first image intensifier (26) and the viewing screen (48), thereby providing the viewer with a virtual, orthoscopic image (A"B"C") of the object (ABC) with full horizontal and vertical parallax.

Abstract: A low intensity X-ray and gamma-ray spectrometer 10 is disclosed for imaging, counting, and energy resolving of single invisible radiation particles. Spectrometer 10 includes a converting device 20 for converting single invisible radiation particles to visible light photons. Another converting device 24 converts the visible light photons to photoelectrons. A fiber optics coupling device 22 couples together converting devices 20 and 24. An intensifying device 26 intensifies the photoelectrons by an average gain factor of substantially 10.sup.4 -10.sup.7. Intensifying device 26 is an anti-ion feedback microchannel plate amplifier which is operated substantially below saturation. A displaying device 32 displays the intensified photoelectrons. Displaying device 32 indicates the spatial position, number, and energy of the incoming single invisible radiation particles.

Abstract: A radiation to visible light converter is combined with a visible light intensifier. The converter is a phosphor or scintillator material which is modified to block ambient light. The intensifier includes fiber optics input and output face plates with a photocathode-microchannel plate amplifier-phosphor combination. Incoming radiation is converted to visible light by the converter which is piped into the intensifier by the input fiber optics face plate. The photocathode converts the visible light to electrons which are amplified by a microchannel plate amplifier. The electrons are converted back to light by a phosphor layer and piped out for viewing by the output fiber optics face plate. The converter-intensifier combination may be further combined with it's own radiation source or used with an independent source.
