Explain working of the vidicon camera tube?
The electrical charge produced by an image taken by a Vidicon Camera tube will remain in the face plate until it is scanned or until the charge dissipates. The target material is made of antimony trisulfide.
The type of camera used to photograph Io's volcanoes?
The Vidicon
What is the principle behind the working of vidicon camera?
A vidicon tube is a video camera tube design in which the target material is a photoconductor. The Vidicon was developed in the 1950s at RCA by P. K. Weimer, S. V. Forgue and R. R. Goodrich as a simple alternative to the structurally and electrically complex Image Orthicon.While the initial photoconductor used was selenium, other targets-including silicon diode arrays-have been used. Schematic of vidicon tube. The vidicon is a storage-type camera tube in which a charge-density pattern is formed by the imaged scene radiation on a photoconductive surface which is then scanned by a beam of low-velocity electrons. The fluctuating voltage coupled out to a video amplifier can be used to reproduce the scene being imaged. The electrical charge produced by an image will remain in the face plate until it is scanned or until the charge dissipates. Pyroelectric photocathodes can be used to produce a vidicon sensitive over a broad portion of the infrared spectrum. Prior to the design and construction of the Galileo probe to Jupiter in the late 1970s to early 1980s, NASA used Vidicon cameras on most of their unmanned deep space probes equipped with the remote sensing ability
What are the Types of a television camera tube?
There are several types of television camera tube (also known as pickup tubes). There is the image dissector, the iconoscope, the Super-Emitron image iconoscope, the Orthicon and CPS Emitron, the image orthicon, and Vidicon. There are also currently several new technologies being developed making several new types of pickup tubes
What is the use of a video camera?

Why did Apollo 12 plan fall through to broadcast color TV?
Human error on the part of LMP Al Bean. When moving the camera into position he accidentally pointed the lens directly at the sun. Because the camera had no lens cap, the direct, intense sunlight burned out the camera's vidicon tubes, rendering the camera inoperable.
Why didn't Apollo 12 broadcast from the moon?
They did broadcast audio, but they were unable to broadcast television because, while moving the T.V. camera into position, LMP Alan Bean accidentally pointed the camera lens directly at the unfiltered sun, burning out the vidicon tubes inside the instrument.
Can a person post hidden camera videos on you tube?
only if its a hidden camera from your uncle's shower
What is the function of a Plumbicon vacuum tube?
The Plumbicon (trademark of Phillips)is an imaging tube, think of it as the active part of a camera.
Is it safe to take vidicon Valium and codeine cough syrup together?
no it is not safe
