330-PS-2484 (USN 705503):  Navy’s Underwater TV Camera Will Act As “Seeing Eye”.  A movie camera, right, is used to take a movie of the picture that is sent out by the underwater TV Camera.     As far as can be determined, the camera was first used for evaluation during the Bikini Atoll bomb test (Operation Crossroads) in 1946.  After the camera is lowered into the water, it is manipulated by remote control from the ship above.  It electronically records a picture that is transmitted to a scope or television screen on the ship Engineers can either check the scope as it records or they can use a movie camera to record the action on film for a permanent reference.  Diving time is reduced and the camera can be raised and lowered rapidly without danger of “bends” that would attack a human diver under similar circumstances.  The new camera was developed by the Bureau of Ships, Department of the Navy.  The David Taylor Model Basin was largely responsible for the experimental applications and evaluation of the new process.   Photograph released January 29, 1952.  (5/26/2015).
