Title: Apparatus for reproducing an image of an object
IPC: G01S7/62
Filed: 1945-12-06
Abstract: 608,769. Local viewing. FARNSWORTH TELEVISION & RADIO CORPORATION. Dec. 6, 1945, No. 33027. Convention date, May 11. [Class 40 (iii)] [Also in Group XL (a)] In a local viewing system, the object to be viewed is scanned by a searchlight beam, the 'light reflected from the object forming an image on the photosensitive cathode of an image transformer, the cathode portion of which is arranged to perform the same scanning motion as the searchlight beam, while the screen portion is fixed, whereby the image formed on the screen scans the screen to produce a composite image of the whole object. A searchlight 1, which preferably generates infra-red light in the wavelength range 8000-10,000 angstroms, is coupled by a rod 11 to driving mechanism, Fig. 3 (not shown), whereby it is caused to perform a spiral scanning motion. The searchlight is rigidly connected to the lightreceiving portion 7 of an image transformer, which is flexibly connected through a bellows 47 to the conical portion 45 which is rigidly held by a support 46. Preferably, the light beam from the searchlight is interrupted (e.g. at 30 c/s) by means of the circuit 48 so that overlapping portions of the object are successively illuminated. Light reflected from the object is focused by lens 5 on to the photosensitive cathode 6 of the image transformer which has an angle of view equal to the angle subtended by the searchlight beam. The electron image produced is focused on to the screen 44, the image performing a scanning motion across the screen corresponding to the motion of the portion 7 of the tube so that by using a long after-glow screen a composite image of the object scanned is formed. In an alternative embodiment, the conical portion 45 of the tube moves with portion 7 so that successive images are formed on the same position on the screen 44 which in this instance has a short after-glow. The light from the screen 44 is projected on to a fixed screen 55 on which the composite image is produced. The searchlight 1 may be stationary, the scanning motion of the beam being produced by a moving mirror system.
