Abstract

1,154,403. Cathode ray storage display tubes. INTERNATIONAL STANDARD ELECTRIC CORP. 17 June, 1966 [22 June, 1965], No. 27104/66: Heading H1D. In a method of comparing a reference image and an optical image, a high velocity electron beam from photocathode 16 in a pattern corresponding to either one of the images, generates a charge pattern on storage screen 21 comprising wire mesh covered with Mg F or ZnS for instance. Subsequently a low velocity beam of electrons emitted from the same photocathode in a pattern corresponding to the other image passes through the storage electrode only in areas of overlap of the two images and forms the display on phosphor screen 28, or alternatively electron multiplier 39 (Fig. 2, not shown) may be included with split anode collector 40 (e.g. semicircular segments as in Fig. 7 (not shown) or quadrants) for relative rotation measurements for example. In Fig. 2 (not shown), disc electrode 35 with a pin hole aperture may be used to modulate a writing beam from a small uniformly illuminated portion of the photocathode or for comparing an image represented by the electrical input signals to electrode 35 with an image already on the storage electrode. The pencil beam may scan in a raster as in a commercial TV system. Fig. 4 (not shown) includes second storage electrode 21a associated with elements analogous to the first stage cylindrical anode 26 (the second stage anode preferably being twice as long as the first stage anode), focusing solenoid 32 and horizontal and vertical deflection coils 33 and 34 and collector grid 20. A flood beam of low velocity electrons, accelerated to a high velocity on emergence from storage electrode 21, transfers a charge pattern from storage electrode 21 to storage electrode 21a. A second image then stored on the former electrode may be compared by a further flood beam. The image size may be adjusted by electrostatic or magnetic optics. Electrostatic and/or magnetic focusing and deflection may be used.
