What is the function of the deflecting coils in a television camera tube?

• A. To produce the electron beam
• B. To control the electron beam
• C. To send the video signal
• D. To capture the image

Answer: (B)

The function of the deflecting coils in a television camera tube is to control the electron beam. These coils create magnetic fields that can steer the electron beam to different locations on the camera tube's target, enabling the precise positioning of the beam. This deflection is crucial for scanning the image, as it allows the beam to move horizontally and vertically across the target surface in a controlled manner. By adjusting the direction of the electron beam, the deflecting coils help ensure that each part of the image is captured accurately, resulting in a complete video signal that can then be processed further or transmitted. This control contributes to the quality and fidelity of the image produced by the camera.
