The New Image Isocon — Its Performance Compared to the Image Orthicon

  • E. M. Musselman
Part of the Optical Physics and Engineering book series (OPEG)


The construction and operating principles of the image isocon and the image orthicon from the photocathode to the storage target are identical. Both utilize low-velocity electron-beam scanning to extract the output signal, but between the target and the electron gun there are important differences. The image isocon camera tube derives its video signal only from scanning-beam electrons that are scattered by the storage target, whereas the image orthicon accepts all of the returned beam for amplification. The electron-optical system, designed to minimize return-beam scan, permits separation of the scattered and reflected portions of the electron beam.
