Abstract :
An experimental optical mixer for a superheterodyne receiver has been constructed for the detection of beats in the 2-4 Gc region. This phototube incorporates an image dissector with a traveling-wave tube helix structure. It can be used to search an image field by electronic scanning for optical beats. Construction details and test results are presented.
