    摘要： A viewing system for improving an image, and particularly designed for use with infrared and low light level inputs. A viewing system having first and second electrodes mounted in spaced relation with a gap therebetween, an electric power source for producing an electric field in the gap attracting electrons toward one electrode and positive charge toward the other, a photoresponsive layer on the gap face of the first electrode with radiation directed onto the layer through the first electrode producing an electrostatic charge image at the gap, and a plurality of electrophoretic particles dispersed in a dielectric liquid in the gap, with the particles being selectively deposited at the second electrode as a function of the electrostatic charge image. In the preferred embodiment, the deposited particles are viewed with a dark field illumination system whereby light is scattered to the viewing position by the deposited particles. Cascaded systems and systems incorporating image intensifiers are also disclosed.

    摘要： An electrostatic imaging chamber providing a real time visual image. An imaging chamber with electrophoretic particles in the electrode gap, with the particles being selectively moved to a transparent electrode as a result of the electrostatic charge image formed by incoming radiation. An imaging chamber which can be cyclicly operated at a relatively high repetition rate, typically 10 to 20 images per second, thereby providing real time viewing of the object. A conductivity control layer at the gap for discharging the electrostatic charge image each cycle after viewing.

    摘要： Apparatus and method for improving contrast in the visual image formed by toner deposited on an electrostatic image such as is formed in electronradiography. Electrophoretic toner particles and a dye are dispersed in a liquid, with the particles being deposited onto a substrate which carries the electrostatic image, with the selectively attracted particles forming the visual image. The visual image is viewed by reflected or scattered light with the light having a color emission spectrum substantially corresponding to the absorption spectrum of the dye for absorbing and thereby eliminating unwanted light.
