What is the meaning of iconoscope?
Definition of iconoscope : a camera tube containing an electron gun and a photoemissive mosaic screen of which each cell produces a charge proportional to the varying light intensity of the image focused on the screen.

What is image Orthicon tube?
Definition of image orthicon : a camera tube that is similar to the iconoscope or the orthicon and uses secondary emission and electron multiplication to produce the voltages that are subsequently amplified and transmitted as television-picture signals.
Who invented the video camera tube?
Lubszynski, Rodda, and McGee realized that the best solution was to separate the photo-emission function from the charge storage one, and so communicated their results to Zworykin. The new video camera tube developed by Lubszynski, Rodda and McGee in 1934 was dubbed “the super-Emitron”.
How did the image dissector work?
An image dissector, also called a dissector tube, is a video camera tube in which photocathode emissions create an “electron image” which is then scanned to produce an electrical signal representing the visual image.

What is Plumbicon camera tube?
The Plumbicon is a camera tube of the vidicon type which utilizes a layer of lead oxide (PbO) for the photosensitive target instead of the more usual photoconducting layer of Sb2Sa employed in standard vidicons.
What is the importance of deflection coils in the TV camera?
Deflection coils These coils must be precisely designed to preserve the focus of the scanning spot no matter where it falls on the screen, and the magnetic fields they produce must be so distributed that deflections occur at uniform velocities.

What is basic principle of TV camera?
an electronic device that converts an optical image into a sequence of electric pulses, or video signal. The first (input) element of the television transmission chain, it picks up the image being transmitted. It is the principal component of the television camera.
